She divides the park into 10 rectangles of equal area. She then randomly selects five trees to measure from each area. She measures 50 trees that are closest to the parking lot. She sorts the data set by tree identification code. She uses random number generator to select the first tree to measure. She then selects every 30th tree in the data set until her sample contains 50 trees. She sorts the data set by location and then gives each tree a unique number ranging from 1 to 1000. She selects the trees to measure by creating a list of 50 randomly generated numbers between 1 and 1000. She divides the data set into five groups, one for each species of tree in the park. She then selects two of the groups at random and forms her sample from the individuals in those groups.

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.
