Chp 1 : Data Analysis

Front

Frequency table

Back

shows the number of individuals having each value.

Front

Relative frequency table

Back

shows the proportion or percent of individuals having each value.

Front

Bar graph

Back

shows each category as a bar. The heights of the bars show the category frequencies or relative frequencies

Front

pie chart

Back

shows each category as a slice of the “pie.” The areas of the slices are proportional to the category frequencies or relative frequencies.

Front

Two-way table

Back

a table of counts that summarizes data on the relationship between two categorical variables for some group of individuals.

Front

Marginal relative frequency

Back

gives the percent or proportion of individuals that have a specific value for one categorical variable.

Front

Joint relative frequency

Back

gives the percent or proportion of individuals that have a specific value for one categorical variable and a specific value for another categorical variable.

Front

Conditional relative frequency

Back

gives the percent or proportion of individuals that have a specific value for one categorical variable among individuals who share the same value of another categorical variable (the condition)

Front

Side-by side bar graph

Back

displays the distribution of a categorical variable for each value of another categorical variable. The bars are grouped together based on the values of one of the categorical variables and placed side by side.

Front

Segmented bar graph

Back

displays the distribution of a categorical variable as segments of a rectangle, with the area of each segment proportional to the percent of individuals in the corresponding category
