Research Project 1 dataset, which is given as an Excel file, contains actual research data collected from a random sample of N = 340 certified flight instructors (CFIs). The dataset consists of 10 independent variables (IVs) and one dependent variable (DV). A description of each variable follows.

X₁ = Participants' gender

X₂ = Participants' age in years X₃ = Participants' race/ethnicity X₄ = Participants' marital status

X₅ = Participants' highest level of education

X₆ = Total years participants have held a CFI certificate

X₇ = Participants' total hours dual given

X₈ = Participants' total hours dual given in previous 90 days

X₉ = Participants' total flight time (in hours)

X₁₀ = Types of certificates participants current hold

Y = Complacency scores, which were measured on a 7-item Likert scale ranging from 1 = Strongly Disagree to 5 = Strongly Agree. Thus, scores could range from 7 to 35, with higher scores indicating a greater likelihood toward complacency as a flight instructor.

Question:

Explain how you would determine the measure of central tendency for X₁₀?
