The table you've provided looks like a summary of descriptive statistics for variables in a study. From the information given, it seems like the table contains the mean, standard deviation, and sample size (N) for various variables. These include Age Group, Psychological Impact, Cognitive Impact, Social Influence, Behavioral Changes, and Satisfaction & EngagementIn a regression analysis, descriptive statistics like these can provide valuable insights into the central tendency, variability, and sample size for each variable. Here's a general interpretation of the table in the context of regression analysis:

1. Mean (Wean): This represents average value of the variable in the sample. For example, mean of Psychological Impact is 2.30, Cognitive Impact is 21, and so on2. Standard Deviation: This indicates the spread or variability the data around the mean. A higher standard deviation suggests greater variability in the data, whereas a lower standard deviation suggests the data points are closer to the mean.

2. Sample Size (N): This refers to the number of observations or data included in the analysis for each variable. A larger sample size gives more reliable estimates.

In a regression analysis, these descriptive statistics can you understand the distribution and variability of the variables being analyzed. They can also be used to assess the precision and reliability of the regression results.

It's important to note that without the full context of the regression analysis, such as the specific model being estimated, the and independent variables, and the research question, it's challenging to provide a more specific interpretation. If you have more detailed information about the regression analysis or specific questions about interpreting regression results, feel free to provide additional context for a tailored response.

The values provided in the model summary are essential in understanding the and accuracy of a regression model. Here's the interpretation for each of these statistics:

1. R-squared (R2): This is a measure of how well the variables explain the variability of the dependent variable. It ranges from 0 to 1, with 1 indicating that the independent explain all the variability of the dependent variable. A higher R value suggests that the independent variables are better at explaining the variation in the variable.

2. Adjusted R-squared (Adjusted R2 This is similar to R2 but takes into account the number of independent variables in the model and adjusts for the degrees of freedom. It penalizes addition of unnecessary independent variables that do not improve the model. The adjusted R2 is often preferred when comparing models with different numbers of independent variables.

3. R: The correlation coefficient (often denoted as "R") measures the strength and direction of the relationship between the independent and dependent variables. It ranges from -1 to 1, where 1 indicates a perfect positive relationship, -1 indicates a perfect negative relationship, and 0 indicates no relationship.

4. Standard Error of the Estimate: This statistic indicates the average distance that the observed values fall from the regression line. It provides a measure of the accuracy of the prediction made by the model. A lower standard error of the estimate indicates that the's predictions are more accurate.

In summary, R2 and adjusted R2 information about how well the independent variables explain the variability of the dependent variable, R indicates the strength and direction of the relationship, and the standard error of the estimate gives a measure of the accuracy of the model's predictions. These are crucial indicators for assessing the quality and reliability of a regression model

R2 and adjusted R2 are checked in regression analyses to assess how well the chosen independent variables explain the variability of the dependent variable. These metrics provide insights into the goodness of fit of the regression modelR2 helps in understanding the proportion of the variance in the dependent variable that is explained by the independent variables. It ranges from 0 to 1, where 1 indicates that the independent variables all the variability of the dependent variable. However, R2 can be artificially inflated when more independent variables are added to the model, even if they do not meaningfully to explaining the dependent variable. This is where adjusted R2 comes in.

Adjusted R2 takes into the number of independent variables in the model and adjusts for the degrees of freedom. It penalizes the addition of unnecessary independent variables that do not the model's explanatory power. Therefore, it's important to check both R2 and adjusted R2 to ensure that the chosen independent variables are truly contributing to explaining the dependent variable and that the model is not overfit.

The main difference between metric and non-metric data lies in the level of measurement and the nature of the data.

Metric data, also known as quantitative or continuous data, is measured on a scale that has a meaningful zero point and equal intervals between values. Examples of metric data include measurements such as height, weight, temperature, and income. These data undergo mathematical operations such as addition, subtraction, multiplication, and division, and can be subjected to various statistical analyses such as mean, standard, and correlation.

On the other hand, non-metric data also known as qualitative or categorical data, represent categories or groups and do not have a numerical value. This type of data cannot be on a meaningful numerical scale. Examples of non-metric data include gender, ethnicity, job role, and favorite color. Non-metric data are analyzed using measures of frequency and percentages, and statistical tests like chi-square test and Fisher's exact test.

Understanding the distinction between metric and non-metric data is vital in selecting the appropriate statistical analysis methods visualization techniques for a given dataset.

Actually, there's a slight correction to make here. Metric data is typically referred to as interval or ratio data, while non-metric data is usually called ordinal or nominal data.

• Metric data: Interval or ratio data has a meaningful zero point and equal intervals between values. Examples include temperature, weight, and income.
• Non-metric data: Nominal and ordinal data do not have numerical significance in their values. Nominal data represents categories without any order, while ordinal data represents categories with a specific order or rank.

So, to clarify, metric data is associated with interval or ratio measurements, and non-metric data includes both ordinal and nominal categories.

In the Kaiser-Meyer-Olkin (KMO) test and Bartlett's test of sphericity, we don't use approximate chi-square and degrees of freedom (df) because these tests are specifically designed to assess the suitability of the data for factor analysis, rather than hypothesis testing.

The KMO test measures the sampling adequacy for factor analysis by examining the partial correlations between variables and is used to determine if the data is suitable for factor analysis. Bartlett's test assesses whether the variables are related (correlated) or not, which is a prerequisite for factor analysis.

Both KMO and Bartlett's test focus on assessing the overall strength of the relationships among variables in the dataset, rather than hypothesis testing using the chi-square distribution. Therefore, the use of approximate chi-square and degrees of freedom is not applicable in the context of these tests. Instead, these tests provide essential information about the appropriateness of the data for factor analysis.

An R-value of 0.762 indicates a strong positive correlation between the dependent variable (Age group) and the independent variables (Psychological impact, Cognitive impact, Social influence, Behavioral change, and Satisfaction and engagement). This suggests that as the independent variables increase, the Age group also tends to increase consistently.

However, it's important to note that correlation does not imply causation, so while a strong relationship is observed, we cannot determine a causal effect. Further analysis such as regression modeling and consideration of confounding variables would be needed to establish causal relationships.

The value of the correlation coefficient (R) lies in the range from -1 to 1.

• If R = 1, it indicates a perfect positive correlation, meaning that as one variable increases, the other also increases proportionally.
• If R = -1, it indicates a perfect negative correlation, indicating that as one variable increases, the other decreases proportionally.
• If R = 0, it suggests no linear correlation between the variables.

In your context, an R value of 0.762 indicates a strong positive correlation between the Age group (dependent variable) and the independent variables (Psychological impact, Cognitive impact, Social influence, Behavioral change, Satisfaction and engagement).

R2 is checked to assess how well the chosen independent variables explain the variability of the dependent variable in a regression analysis.

Adjusted R2, in the context of regression analysis, is a modified form of R2 that considers the number of independent variables in the model and adjusts for the degrees of freedom. It is checked to determine if the chosen independent variables are truly contributing to explaining the dependent variable (goodness of fit) and to avoid overfitting by penalizing the addition of unnecessary independent variables.

If adjusted R2 = 0.563, it means that approximately 56.3% of the variability in the dependent variable is explained by the chosen independent variables, after considering the number of independent variables in the model. This suggests that the model has moderate explanatory power, but there is still unexplained variability that needs to be considered.

Adjusted R2 is checked to assess the goodness of fit of a model while considering the impact of the number of independent variables in the model. It helps in determining if the chosen independent variables are truly to explaining the dependent variable and also aids in preventing overfitting by penalizing the addition of unnecessary independent variables. Essentially, adjusted R2 provides a more indication of the explanatory power of the regression model.

Adjusted R2 is checked to assess the model's goodness of fit while accounting for the number of independent variables, ensuring that the chosen variables effectively contribute to explaining the dependent variable and preventing overfitting

An adjusted R-squared value of 0.563 suggests that approximately 56.3% of the variability in the dependent variable is explained by the chosen independent variables in the regression model, after considering the number of independent. This indicates a moderate level of explanatory power, with room for improvement.

An adjusted R-squared value of 0.563 would mean that approximately 56.3% of the variability in the Age group, the dependent variable, is explained by the independent variables (Psychological impact, Cognitive impact, Social influence, Behavioral change, and Satisfaction and engagement) in the regression model, after considering the number of independent variables. This indicates a moderate level of explanatory power, suggesting that these independent variables have a notable but not complete influence on the Age group.

An adjusted R-squared of 0.563 means that the independent variables can explain approximately 56.3% of the variation in the age group, showing moderate level of explanatory power.

An adjusted R-squared of 0.563 means that the chosen independent variables can explain about 56.3% of the variation in the age group, indicating a moderate level of predictive power in the model.
