Get 'EDUC298 ATS' data-file of Attitudes toward Statistics from blackboard, and do followings:

Make new variables of M1, M2, M3, M4, M5, & M6 by recoding item30, item31, item32, item33, item34, item35 in dichotomous variables (1 = correct answer, 0 = incorrect answer). (Note: The correct answers on math items are 3, 5, 3, 5, 4, & 2)  

Make a composite math score by summing new math variables. Name it 'Mtotal' (total score on math).

Recode negatively worded items. These items are 2, 4, 6, 7, 10, 12, 14, 15, 16, 18, 20, 25, 27, and 28.  The values of items will be changed as follows: 5 to 1; 4 to 2; 3 to 3; 2 to 4; 1 to 5.

Make a composite variable summing all items (Q1 to Q29) and name it 'Atotal'.

  1. Determine the variables of Q37, Q42, Mtotal, and Atotal as continuous or categorical. Report measures of central tendency (Mean and Median) and variability (Variance and Standard Deviation) for each continuous variable. Report the Mode and Percentages for categorical variables.
  2. Plot the stem-and-leaf plot and boxplot for Mtotal. Describe the hand calculation of median location and upper hinge location of boxplot, and find their corresponding data values.
  3. Plot the histogram for Atotal.  
  4. Report the correlation coefficient between variables of Mtotal and Atotal. Graph the relationship and interpret it.
