Construct a frequency distribution for the following scores: 5  3  3  2  4  3  4  3  3  5  4  1 Based on the frequency distribution, what is: The frequency for a score of 4 [f] The relative frequency for a score of 4 [rf] The cumulative frequency for a score of 4 [cf] The cumulative relative frequency for the score of 4 [crf] **To receive credit for this problem you will need to show your work.

Identify the independent and dependent variables in the problem below: A teacher wanted to test the prediction that the color of ink used to grade papers impacts how students responded to feedback. To test her prediction, the teacher decided that she would grade all of the papers in one of her classes using red ink and grade all of the papers in another class using green ink. She continued to use the same color ink throughout the semester to grade all assignments. At the end of the semester, she had her students fill out a short survey to assess their feelings about the feedback received in class. In particular, she asked the students in both classes how helpful the feedback was. The teacher then compared the average helpfulness ratings in the two classes, to see if the color of ink impacted the helpfulness ratings.  The independent variable is [IV]. The dependent variable is [DV].

Use the scores below to calculate the standard deviation. **Report your answer to 4 decimal places.

Suppose, you have a set of 10 reaction time scores that range from 20-30 seconds with a mean of 25 and a standard deviation of 2. Now suppose, you realize you forgot to add one score to the distribution and you actually have 11 reaction time scores. The score that you forgot was 45. What effect will the addition of the score of 45 have on the average score?

Use the scores below to find the mode. 5, 6, 9, 3, 2, 8, 16, 2

For each variable listed below, indicate if the variable is nominal, ordinal, interval, or ratio.  Type of exercise class (with the values 1 = beginning, 2 = intermediate, 3 = advanced) [class] Number of correct answers on a 10-question quiz. [quiz] Time on task measured with the following scale: 0-10 minutes, 11-20 minutes, 21-30 minutes, 31-40 minutes, 41-50 minutes [activity] Study preference (1= no music, 2 = music) [music]

For each variable listed below indicate the most appropriate measure of central tendency to use to characterize the variable: Major in college: [Major] Age (measured in years): [Age] Starbuck’s coffee sizes (short = 8 oz; tall = 12 oz; grande = 16 oz; venti = 20 oz): [coffee]
