Quiz 1

Use the Dataset associated with this Assignment in Moodle

Directions: Respond to the prompts below. Follow the ‘Do Not’ and ‘Do’ instructions.

DO NOT : · Upload your Excel workbook to Moodle · Copy and paste the dataset values into this document · Upload your work as a Word document in Moodle

DO · Paste or type your responses directly into this document · Save your completed work as a PDF file · Upload your only your PDF file to Moodle

1) In the dataset, select ONE categorical variable and TWO interval level or above variables that you will investigate for this assignment. List your choices here in Table 1.

Table 1

Categorical and Interval/ Ratio level Variables Under Study

Categorical (this must be a different categorical variable that you have not chosen for a previous assignment)	Interval / Ratio
1)	1)
	2)

2) Using the Descriptive Statistics feature , of either JASP or the Data Analysis ToolPak in Excel, generate numerical summary tables for your interval level or above variable choices in Table 1 above. Copy and paste the tables into this document. Ensure that the tables are APA formatted correctly

3) Determine the representative measures of center , for each of your continuous variables, and they associated measure of spread. Type your responses in Table 2 below:

Measures of Center and Spread for the Interval Level or Above Variables

Variable	Measure of the Center	Measure of Spread	Rationale for Measure of Spread Choice

4) Calculate and interpret the correlation for the interval/ratio level variables in Table 1.

5) Generate a scatter plot for the 2 variables you identified as interval/ratio in Table 1. Select one to be the explanatory variable and the other to be the response variable. Place the explanatory variable on the horizontal axis. Copy and Paste the scatterplot here. Ensure that the chart is APA formatted.

6) Describe what the dot pattern in the scatter plot from #5 above.

7) Using the Regression feature, of either JASP or the Data Analysis ToolPak in Excel, generate the 3 Simple Regression output tables for your 2 interval/ratio variables in Table 1. Copy and paste all 3 tables here.

8) Using complete sentences, interpret the Multiple R and R Squared.

9) Using complete sentences, discuss the significance of the simple regression equation.

10) Using complete sentences discuss the significance of the coefficients.

11) Using the Regression feature, of JASP or the Data Analysis ToolPak in Excel, Residual and Normality plots and histograms. Copy and paste the charts here. Ensure that they are correctly APA formatted.

12) Using complete sentences, interpret the Residual plot.

13) Using complete sentences, interpret the Normality plot.

14) Using complete sentences, interpret the histogram.

15) If it makes sense to do so, write out the potential Simple Regression equation. If not, explain why. Enter your response in the table below

16) Select ONE of your interval/ratio variables to use along side your selected categorical variable to perform a one-way ANOVA investigation in JASP. Paste the output tables here.

17) Perform an equal variances assumption check. Post the evidences here.

18) Generate group level descriptive statistics including tables and charts. Enter them here.

19) Are you warranted to run a One-way ANOVA test? Explain.

20) Do you need to run a post hoc test? Explain

21) If you need to run a post hoc test, do so and paste the output tables here.

22) Write an interpretation for the post hoc test results.
