the first class in a relative frequency table 50-59 and the corresponding relative frequency is 0.2. What does the 0.2 value indicate?

Answered in a previous post.

The value 0.2 in the context of a relative frequency table indicates the proportion of the total data set that falls within the first class interval, which in this case is the interval 50-59.

To understand this concept, we need to calculate the relative frequency. Relative frequency is obtained by dividing the frequency of a particular class by the total frequency of all classes. In this case, we are provided with the relative frequency (0.2) for the first class interval.

To get the relative frequency, you need to have the total frequency of all classes. Let's assume we have that information and the total frequency is 100.

Since the relative frequency for the first class interval is 0.2, we can calculate the frequency for that class interval by multiplying the relative frequency by the total frequency:

Frequency = 0.2 x 100 = 20

So, the frequency for the class interval 50-59 is 20. This means that out of the total data set, 20 observations fall within the interval 50-59.

In summary, the value 0.2 as the relative frequency for the interval 50-59 indicates that 20% of the total data set falls within that interval.
