## Using the Nebraska Inmate Survey (NIS), choose 1 dichotomous variable that is of interest to you. Create a bar chart. Copy and paste the results below. Interpret the bar chart.

1. Using the Nebraska Inmate Survey (NIS), choose 1 dichotomous variable that is of interest to you. Create a bar chart. Copy and paste the results below. Interpret the bar chart.
2. Using the Nebraska Inmate Survey (NIS), choose 1 variable that is ordinal, interval, or ratio and is of interest to you. Create a pie chart. Copy and paste the results below. Interpret the pie chart.
3. Using the Nebraska Inmate Survey (NIS), choose 1 NEW variable that is ordinal, interval, or ratio and is of interest to you. Create a histogram. Be sure to display the normal distribution. Copy and paste the results below. Interpret the histogram. Is your variable normally distributed?
4. Using your own words, explain what it means if two variables are correlated. Next, using the Nebraska Inmate Survey (NIS), choose 2 NEW variables that are both ordinal, interval, or ratio and of interest to you. You will need an independent variable and a dependent variable. Indicate below your hypothesis noting which variable is your independent and dependent variable. For example: Those who are more highly educated are less likely to have been on probation. Independent variable: Education; Dependent variable: Probation. Make sure your temporal order is logical.
5. Using your own words, describe why scatterplots are useful. Create a scatterplot using your variables from number 4. Copy and paste the results below. Interpret the scatterplot. Do the variables appear to be correlated?
