Activity 2_A: Construct a histogram for theYear_9variable. Upload the histogram.

Activity 2_B: Construct a boxplot for theYear_9variable. Upload the boxplot.

Activity 2_C: Describe the shape of the distribution of theYear_9variable using statistical terminology.

Activity 2_D: If you were presenting these data (e.g., conference presentation, presentation to coworkers), would you use the histogram or boxplot?Explain why.There are many possible correct answers.

Activity 2_E: Construct side-by-side boxplots to compare theYear_7variable bySex. Upload the side-by-side boxplots.

Activity 2_F: Construct side-by-side boxplots to compare theYear_16variable bySex. Upload the side-by-side boxplots.

Activity 2_G: Compare your side-by-side boxplots forYear_7andYear_16. Do the heights of females and males appear to be more similar or more different from each other as they get older?Explain how you used your side-by-side boxplots to determine this. In other words, explain what you were looking for in the graphs.

Activity 2_H: Construct a simple scatterplot withYear_7on the x-axis andYear_16on the y-axis. Upload the scatterplot.

Activity 2_I: Describe the relationship betweenYear_7andYear_16. Be sure to mention the direction, form, strength, and outliers.

Activity 2_J: Compute the correlation betweenYear_7andYear_16. Clearly identify your final answer by highlighting or circling it on the output or writing a sentence (e.g., "Pearson's r is XXX").

Activity 2_K: This is the regression model using Year_7 to predict Year_16:

Year_16 = 11.94 + 1.280 Year_7

Identifyandinterpretthe slope.

Activity 2_L: Identifyandinterpretthe y-intercept in the regression model that usesYear_7to predictYear_16shown in part K. Why or why not is this a realistic value?

Activity 2_M: Construct a scatterplot with groups withYear_7on the x-axis,Year_16on the y-axis, andSexas the grouping variable.

Activity 2_N: Describe the relationship betweenYear_7,Year_16, andSex. Be sure to mention all three variables.
