The following is a made-up data set that contains scores from 10 people regarding their self-rated happiness and their self-rated level of stress. Happiness was rated on a scale of 1 (not happy at ll) to 10 (extremely happy). Stress was rated on a scale of 1 (not experiencing stress at all) to 10 (experiencing extreme amounts of stress) Subject ID number Happiness Scores Stress Scores 10 1. Using the data set above, report the range of "happiness". Show all of your work to receive full credit. (1 point - .5 point for correct answer and .5 point for showing work) Formula: R = HS - LS 2. Using the data set above, compute the mean for the variable "happiness" by hand. Show all of your work to receive full credit. (1 point - .5 point for correct answer, .5 point for showing all Work) Formula: variance = 5- Mean formula: x = _ X /N 9. Using the data set "Problem Set 2 Data Set" found on Canvas, compute the standard deviation, the variance, and range of the variable "X1" using SPSS. For credit, be sure to include your 3. Using the data set above, please report the median for the variable "happiness" by hand output. (1 point - .5 point for getting the correct output and .5 point for including the output) HINT: when you have an even number of observations, there is no "middle" number. Thus, you compute the average of the two middle numbers. Show your work to receive full credit. (1 point - .5 point for correct answer, .5 point for showing all work) 10. Using the output that you generated with SPSS for the previous item (#9), report the standard deviation, variance, and range of X1 using short sentences. (.5 point - for all correct answers). 4. Using the data set above, please report the mode of the variable "stress". (1 point - for correct answer) 11. Using your answer for the previous item (#10), please interpret the standard deviation of X1; in other words, say what this number means conceptually. (.5 point for correct answer) 5. How frequent was the value of the mode of "stress"? In other words, how many times did the Problem Set 2 Data Set.sav [DataSet1] - IBM SPSS Statistics Data Editor value of the stress mode occur in the sample?
