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 the scores are within that interval.

The value 0.2 in the context of a relative frequency table indicates the proportion or percentage of the total data set that falls within a specific class. In this case, the first class range is 50-59, and the relative frequency is 0.2.
To understand what the 0.2 value represents, you need to know that relative frequency is calculated by dividing the frequency of a specific class by the total frequency of all classes. In other words, it is the fraction of the whole data set that belongs to a particular class.
In this example, if you were given the total frequency or count of data, you would multiply that value by 0.2 to find out how many data points fall within the class range of 50-59. This relative frequency of 0.2 indicates that 20% of the total data set falls within the 50-59 class range.
