QUANTITATIVE RESEARCH METHODS - ASSIGNEMTN 23Assignment 2A2.1: Chapter 4, Problem 4.1, Descriptive Statistics for the Ordinal and Scale VariablesA2.1.a. Narrative of the ProcessI utilize the hsbdata.sav to generate the Descriptive Statistics tables shown in outputs 4.1.a and4.1.b. I started by selecting analyze and highlighting all the “ordinal and moving them to thevariables box, afterwards from the “Options” box, I checked all essential boxes and hit continueand ok to generate the Descriptive Statistics table 4.1a. I replicated the very same method butthat period with all the variables named “Scale” to generate the Descriptive Statistics table 4.1b.I then cut and paste both tables.A2.1b. Interpretation of the FindingsAll the variables categorized as ordinal and scale are incorporated in both descriptive statisticstables. They as well incorporate the number of subjects (N) the Minimum (lowest), andMaximum (highest) scores, the Mean (or average) for every variable, the standard deviation andthe Skewness statistic. Error of the skewness.The Valid N is 69 for the output 4.1a. and 71 forthe output 4.1b. The variables father’s education, item01, motivation, and competence have oneor two participants with missing data.The mean is 5.2433 for the variable visualization test. For the variable math achievementtest, the skewness is .044 and the standard error is .277. It illustrates that the math achievementtest scores are nearly normally distributed since the skewness statistic is within the range of +1 to-1. For the mosaic pattern test, the minimum score is -4.0. It is comparable the lowest possiblescore given to the mosaic pattern test. This signifies that some subjects have scored the lowestprobable score in the mosaic pattern test. For the variable Competence Scale, the skewnessstatistic is -1.634. This demonstrates that the variable did not follow the normal distribution.
