This question is in honor of my alma mater, Texas Christian University. Young et al. (2006) studied horned lizard (aka horned frogs) survival at the hands of predators. They measured the length (in mm) of the squamosal horn of living horned lizards and of recently killed horned lizards to see if this structure might affect survival. For each outcome (alive or dead), they obtained data from 10 individuals from three populations. Live individuals were obtained from Lubbock, Austin, and Waco; dead individuals were obtained from Stillwater, Norman, and San Antonio. The lengths of the squamosal horn are given below for each population: Condition Population Horn Length Condition Population Horn Length Alive Lubbock 25.2 Dead Stillwater 21.4 Alive Lubbock 26.9 Dead Stillwater 23.9 Alive Lubbock 26.6 Dead Stillwater 23.2 Alive Lubbock 25.6 Dead Stillwater 22.6 Alive Lubbock 25.7 Dead Stillwater 22.5 Alive Lubbock 25.9 Dead Stillwater 19.3 Alive Lubbock 27.3 Dead Stillwater 23.5 Alive Lubbock 25.1 Dead Stillwater 23.4 Alive Lubbock 30.3 Dead Stillwater 19 Alive Lubbock 25.6 Dead Stillwater 21.7 Alive Austin 26 Dead Norman 20.2 Alive Austin 24.6 Dead Norman 26.7 Alive Austin 25.6 Dead Norman 21.7 Alive Austin 25.3 Dead Norman 21 Alive Austin 23.5 Dead Norman 23.9 Alive Austin 24.5 Dead Norman 24.6 Alive Austin 23.3 Dead Norman 21.6 Alive Austin 26 Dead Norman 25.3 Alive Austin 23.9 Dead Norman 25 Alive Austin 27.3 Dead Norman 25.2 Alive Waco 25.4 Dead San Antonio 15.2 Alive Waco 25.5 Dead San Antonio 22.9 Alive Waco 21.4 Dead San Antonio 21.4 Alive Waco 23.8 Dead San Antonio 23.9 Alive Waco 25.5 Dead San Antonio 17.2 Alive Waco 19.2 Dead San Antonio 15.5 Alive Waco 20.7 Dead San Antonio 22 Alive Waco 19.2 Dead San Antonio 22 Alive Waco 25.5 Dead San Antonio 23.1 Alive Waco 20.5 Dead San Antonio 20.7 The question asks which analysis method (two-factor ANOVA; nested ANOVA; repeated-measures ANOVA) is correct for these data and why, and then to perform the analysis accordingly. Additionally, the data from a survey of college students concerning books read during the past six months is provided, with probability distribution: x and P(X=x). The task is to compute the variance of X, rounded to two decimal places.
