1. What is the difference between relative frequency and frequency for each data value inTable 2.42? The frequency for each data value is the proportion of all the data points which have that valuenumber of times that data value occursClick for List. The relative frequency for each data value is the number of times that data value occursproportion of all the data points which have that valueClick for List.
2. What is the difference between cumulative relative frequency and relative frequency for each data value? The relative frequency for each data value is the proportion of all the data points which have that valueproportion of all the data points which have that value or lessClick for List. The cumulative relative frequency for each data value is the proportion of all the data points which have that valueproportion of all the data points which have that value or lessClick for List.
