10. What type of distribution do the complacency (Y) scores form, and what is the shape of this distribution if the outliers are removed? Justify your response relative to the three measures of central tendency.

The data file labeled Ch 2 Exercises Part B contains research data collected from a ran- dom sample of N = 340 certified flight instructors (CFIs). The data set consists of 10 inde- pendent variables (IVS) and one dependent variable (DV). A description of each variable follows. X = Participants' biological sex (male or female) X2 Participants' age in years X3 = Participants' race/ethnicity X4 X5 X6 X7 Participants' marital status Participants' highest level of education Total number of years participants held a CFI certificate Participants' total hours dual given X8 = Participants' total hours dual given in previous 90 days Participants' total flight time (in hours) X9 = X10 Types of certificates participants currently hold Y= Complacency was assessed using a 7-item instrument measured on a traditional 5-point Likert response scale. Thus, scores could range from 7 to 35, with higher scores indicating a greater likelihood toward complacency as a flight instructor.
