What are the independent and dependent variables for the following examples? What statistical test would you use for each of the following scenarios? Do the best you can based on the lectures. Dahlia is interested in how depression impacts willingness to exercise and go to the gym. In order to do this, she has to have a large sample size, so she decides to send out a survey to all college students at SUNY Cortland. Once she receives 80% of the surveys back from the students she begins to record the data. Because of the responses to her questionnaires, she will not have normally distributed data. In this case, what might be the best statistical test to use to determine whether going to the gym/willingness to exercise is impacted by depression?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
