It is an area diagram and can be defined as a set of rectangles with bases along with the intervals between class boundaries and with areas proportional to frequencies in the corresponding classes. A histogram is a graph used to represent the frequency distribution of a few data points of one variable. For example, the dot plots show that the travel times for students in South Africa are more spread out than for New Zealand. The x-axis of a histogram reflects the range of values of a numeric variable, while the y . If the points track the straight line, your data follow the normal distribution.

Use the data to draw a histogram that shows your class's travel times. in the same histogram, the number count or multiple occurrences in the data for each column is represented by the y-axis. Research source Here are his findings from observing and writing down the wait times spent by 20 customers: The corresponding histogram with 5-second bins (5-second intervals) would look as follows: Jeff can conclude that the majority of customers wait between 35.1 and 50 seconds. Bimodal: A bimodal shape, shown below, has two peaks. Histogram example: student's ages, with a bar showing the number of students in each year. Enter the number of bins for the histogram (including the overflow and underflow bins). See also why do explorers explore.
