o Calculate measures of central tendency and variability:
Using Jamovi or SPSS, calculate the mean, median, mode, standard deviation, range and confidence intervals for the numeric variables:
-GPA
-Hours_Studied_Per_Week
-Sleep_Hours_Per_Night
-Stress_Level
-Mental_Health_Score.
o Consider whether any of these variables appear to follow a normal distribution based on these statistics. How might the shape of the distribution affect your understanding of central tendency and variability?
o Do any of the distributions appear to be skewed? If so, in what direction? How might this skewness impact the interpretation of the data?
4.
A. Calculate and interpret confidence intervals for the mean of GPA and hours studied per week. Discuss what these intervals indicate about the population parameters.
B. Create a frequency table and bar chart: Choose one categorical, nominal, or ordinal variable. Create a frequency table and bar chart for the same variable.
C. Create a histogram and scatterplot: Create a histogram of GPA. Does the shape of the histogram suggest that GPA is normally distributed?
Then, create a scatter plot of Hours_Studied_Per_Week vs. GPA. Based on the scatterplot, describe any patterns you observe. How might studying hours relate to GPA based on the plot?
o Write a brief report (1 page) summarizing your findings in APA format, including:
o Introduction: Purpose and variables examined
o Method: Dataset, analyses performed, software used
o Results: Key findings from descriiptive statistics and visualizations
o Discussion: Interpretation, implications, limitations
o References:
o Appendix: Essential tables and figures
