LAB Worksheet – Descriptive Tables and Statistics Perform the necessary descriptive and frequency analysis on the survey data in order to answer the questions in each part of the worksheet. PART 1: Frequency Table for Year in School Create a frequency table for the Year in School variable in JASP to answer the questions below. Name the analysis “Frequencies for Year in School” 1. How many participants took the survey (N)? 101 2. How many of the participants in the survey are freshman? 69 3. Which year in school had the lowest percentage of participants? sennior 4. What is the cumulative percentage (%) of freshman plus sophomores (state as one value)? 82.178% 5. Copy and paste only the frequency table for the Year in School distribution below (table must be sequenced in ascending academic year order). 6. Frequency Tables Frequencies for Year in School Year in School Frequency Percent Valid PercentCumulative Percent Freshman 69 68.317 68.317 68.317 Sophomore 14 13.861 13.861 82.178 Junior 15 14.851 14.851 97.030 Senior 3 2.970 2.970 100.000 Missing 0 0.000 Total 101 100.000 PART 2: Age and Credit Hours descriptive analysis Create a descriptive table and frequency table for both of the variables age and credit hours to answer the questions below. Name the analysis “Descriptives for age and credits” Include the following statistics: Valid, mode, median, mean, range, minimum and maximum. 1. What is the average age of all participants? 19 2. Approximately half of the participants (median) are taking up to how many credits? 16.000 3. What percentage of participants are taking less than 15 credits? 19.802 4. What is the age of the oldest sophomore? 20 5. What percentage of sophomores are age 19? 57.143% PART 3: Survey Items descriptive analysis There are 5 survey items related to stress in the survey. Create a frequency table for each survey item in order to answer the questions below. Name the analysis “Descriptives for Survey Items”.

1. How many participants agree (values of 4 or 5) that they avoid social situations when they are stressed? 46 2. What was the most highly agreed upon question (values of 5)? I feel stressed when I have a big exam 3. What was the most highly disagreed upon question (values of 1)? My family causes stress in my life 4. What percentage of participants felt ambivalent (value of 3) about feeling overwhelmed with school or work? 24.752% 5. Do more students agree with (values of 4 or 5) or disagree with (values of 1 or 2) the statement that unfamiliar situations make me stressed? More students agree than disagree. PART 4: Total Stress Score descriptive analysis When trying to compute the new column, JASP crashed and didn’t save any previous descriptives except for the things loaded into this doc already. Create a Total Stress Score variable in the data set that sums the scores for each of the 5 survey items. You must first convert the measurement for each variable from ordinal to scale in order to calculate the sum. NOTE: High total scores indicate a high level of stress while low total scores represent low stress. Create a descriptive statistics table and a frequency table (change the minimum distinct values to 20) for Total Stress Score to answer the questions below. Name the analysis “Descriptives for Total Stress Score”. Include the following statistics: Valid, mode, median, mean, range, minimum and maximum. 1. What are the highest and lowest total stress scores on the survey? Lowest = 7, Highest = 25 2. Was the students average total stress score above or below the median point of the scale (15.00)? Above 3. What percentage of students had a total stress score from 7 through 15? 29.703% 4. Filter the dataset to create a subgroup of underclassmen (freshman and sophomores) and copy and paste the resulting descriptive statistics table below. Then create a subgroup of upperclassmen (juniors and seniors) and copy and paste the descriptive statistics table below. Note: DO NOT split the tables in the analysis by Year in School. Underclassmen descriptive table: Descriptive Statistics Sum of stress scores Valid 83 Mode 19.000ᵃ Median 18.000 Mean 17.675 Range 16.000 Minimum 9.000 Maximum 25.000 ᵃ The mode is computed assuming that variables are discreet.
