A delivery service promises that deliveries will occur within a specified time. The service wants to determine how well they are meeting this promise during peak hours and non-peak hours. The dataset for this graph uses two categorical variables, each having two values, which produces four possible combinations that observations can fall within: 1....
Bar charts often compare categories, but that’s not always the case. You just need a discrete variable for the horizontal X-axis. For instance, the bar chart below uses a five-point Likert scale for satisfaction. Likert scale data are ordinal and have discrete values.

You can use bar charts to compare summary values between categories or understand the relationships between categorical variables. However, if you want to use your sample to infer the properties of a larger population, be sure to perform the appropriate hypothesis tests to determine statistical significance.

Bar charts usually present categorical variables, discrete variables or continuous variables grouped in class intervals. They consist of an axis and a series of labelled horizontal or vertical bars. The bars depict frequencies of different values of a variable or simply the different values themselves.
There are four types of bar graphs: vertical bar graph, horizontal bar graph, stacked bar graph, and grouped bar graph. Vertical Bar Graph: It represents the grouped data vertically. Horizontal Bar Graph: It represents the grouped data horizontally.
