A. Did the classmate conduct the correct analysis? Explain.B. Are the results statistically significant? Explain.C. How would you calculate the proportion of variance in base stealing accounted for by birth order?

1. Sulloway and Zweigenhaft (2010) examined the relationship between birth order and risk taking among major league baseball players. They found that first borns were less likely to steal bases than later borns. One of your classmates examined this relationship by watching one season of baseball games by one college team and recording the birth order of the players and whether or not the player stole a base during the season. Birthorder x Stolenbase Crosstabulation Stolenbase Stole at No bases least one stolen base Total Birthorder First borns Count 10 7 17 Expected 12.6 4.4 17.0 count Later Count 16 2 18 borns Expected 13.4 4.6 18.0 count Total Count 26 9 35 Expected 26.0 9.0 35.0 count Chi-Square Tests Asymptotic Significance Exact Sig.
