We investigate a scenario that includes interpreting cumulative relative frequency graphs, using percentiles and quartiles to estimate central tendency and spread within a distribution, and calculating the interquartile range based on the interpretation of the graph.

9 kwi 2022 · The cumulative frequency of a class interval is the count of all data values less than the right endpoint. The cumulative relative frequency of a class interval is the cumulative frequency divided by the sample size.
How to Draw an Ogive Graph. Example question: Draw an Ogive graph for the following set of data: 2, 7, 3, 8, 3, 15, 19, 16, 17, 13, 29, 20, 21, 21, 22, 25, 31, 51, 55, 55, 57, 58, 56, 57, 58. Step 1: Make a relative frequency table from the data.
Cumulative frequency graphs are called ogive graphs. You can also find the relative cumulative frequency from the frequency distribution table by dividing the cumulative frequency of each interval by the total number of observations and then converting it to a percent.
A cumulative relative frequency distribution sums the progression of relative frequencies through all the possible outcomes. Creating this type of distribution entails adding one more column to the table and summing the values as you move down the rows to create a running, cumulative total.
