Assignment

Question #1:

How many variables are in the data file? How many participants?

Question #2:

Within the Analyze menu, where do you find the "Independent-Samples T Test..." command?

Question #3:

What does it mean if someone has a "4" for variable #22 "Negative Emotion (Childhood)"?

Question #4:

What was the exact wording we used in the survey for question #92 "Life Satisfaction"?

Question #5:

Question #6:

What is the cumulative percentage of people who rated themselves as a "4" or lower on the "Play Sports" variable?

Question #7:

Both of the variables have messy-looking histograms, but which variable is more negatively skewed?

Question #8:

You hypothesize that eating too much causes poor health. Make a scatterplot using variable #86 "Physical Health" and #48 "Eat too Much". Add a best fit line. Based on the scatterplot, does it look like your hypothesis is supported? (Remember, the "cause" goes on the X Axis).
