The training director of a company is trying to evaluate three different methods of training new employees. The first method assigns each to an experienced employee for individual help in the factory. The second method puts all new employees in a training room separate from the factory, and the third method uses films and programmed learning materials. The training director chooses 18 new employees assigned at random to the three training methods and records their daily production after they complete the programs. Below are productivity measures for individuals trained by each method. Method 1 Method 2 Method 3 45 59 41 40 43 37 50 47 43 39 51 40 53 39 52 44 49 37 At 0.05 level of significance, do the three training methods lead to different levels of productivity? Use F tabulated value 3.68. (use ANOVA)
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
