Indeed, the value 3 appears four times in the sample, more than any other number Such relative frequencies can also be graphed and represented with a bar chart ( relative frequency bar chart ). Relative Frequency. Now, all the frequencies are divided by the total (928) to give percentages. 5 0 ℎ ≤ 1 . In statistics, a frequency distribution is a list, table or graph that displays the frequency of various outcomes (values) in a data set. Make a Relative Frequency Histogram. This is a common practice, as relative frequency is often used as a predictor of the percentage of times that some value will occur. 2 Descriptive Statistics. 0.14 = 14% students with an F. 0.18 = 18% students with a D. 0.36 = 36% students with a C. 0.24 = 24% students with a B. Two common categories of waves are transverse waves and longitudinal waves. X-axis from 3.5 to 9.5 Remember that the height of each bar in a histogram equals the number of values that are in the range for that bar. • A relative frequency is a frequency divided by the count of all values. For instance, the first relative frequency of an occurrence is two out of 20 and the second relative frequency is five out of 20. Make a double-bar graph of the data.
