Frequency and Cumulative Frequency
In the first video, we are going to use frequency and cumulative frequency.
List: 3, 3, 3, 9, 12, 14, 14, 15, 19, 29, 34, 34, 35, 36, 37
Let’s make a table to group the numbers. Make sure that the intervals are the same for all groups.
Cumulative frequency starts from the first value, and the initial value remains when moving on to the next group.
Representing Frequency and Cumulative Frequency with a Histogram
In the second video, we are going to create histogram.
Let’s use the same list from the first video. Histograms look relatively close to bar graphs with minor changes, but the overall ideas are the same. Mark the x-axis with the desired intervals and the y-axis with the values. Make sure that the values are increasing at a constant rate.
