Question
The relative frequencies for a set of data are shown in the table below.
ValueRelative Frequency10.1520.3030.4540.10
If there are a total of 40 data values, with what frequency does the data value 1 occur?
Provide your answer below:
Dividing each frequency by the total number of data values gives the relative frequency.
Multiplying the relative frequency by the total number of data values gives the frequency.
The data value 1 occurs with relative frequency 0.15 in a data set of 40 values, the frequency of
the data value 1 is0.15(40)=6.
