AVS 5205: Aviation Statistics Fall 2024 Graded Assignment 2 Descriptive Statistics 1. The data file labeled Graded Assignment_2 contains research data collected from a random sample of NV= 340 certified flight instructors (CFIs). The data set consists of 7 independent variables (IVs) and one dependent variable (DV). A description of each variable follows. X1 = Participants' biological sex (male or female) X2= Participants' age in years X3 = Participants' marital status X4 = Participants' highest level of education Xs = Total number of years participants held a CFI certificate X6 = Participants' total hours dual given X7 = Participants' total flight time (in hours) 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. a) Using your statistics software, find the appropriate measures of central tendency and variability for Y and Xi - X7. Complete a chart like the one below. The first two rows are completed for you as a guide (5 points): Table 1.1 Appropriate Measure of Central Tendency Factor Appropriate Measure Appropriate Shape Actual of Central Tendency Measure of Measure of Variability Central Tendency X1 Mode NA Nominal Data Male X2 Mean/Median SD and Range Skewed Left 56.7/60 XA X's X6 X1 b) Prepare a descriptive statistics summary table for all the continuous variables. Use the table below as a guide. (Round to two decimal places.) (5 points). Table 1.2 Descriptive of Continuous Variables Factor M SD Range (L-H)
