The first class in a relative frequency table is 50–59 and the corresponding relative frequency is 0.2. What does the 0.2 value indicate?
20% of scores fall within that interval.
20%
The 0.2 value in the relative frequency table indicates the proportion or percentage of the total data set that falls within the first class, 50-59. Therefore, it means that 20% of the total data values fall within the range of 50-59.
To understand how to calculate relative frequency, you would need the total number of data values in the data set, and the number of data values within the specific class range (50-59). Given that the relative frequency is 0.2, you can use the following formula to find the number of data values in the first class:
Relative Frequency = Number of data values in the first class / Total number of data values
Therefore, if you multiply the relative frequency value of 0.2 by the total number of data values, you will get the number of data values in the first class.
