(Note: If you don't like the groups, then go back and change the group size or starting value and try again.)For example, the size of the class interval for the first class is 30 – 21 = 9. Similarly, the size of the class interval for the second class is 40 – 31 = 9. If we calculate the size of the class interval for each class in the frequency distribution, we’ll find that each class interval has a size of 9.Relative frequency is used to estimate probabilities from experimental data. For a certain number of trials, the probability of ‘success’ is given as; e.g. If you flip an unfair coin 50 times and it lands on heads 20 times then you would use relative frequency to estimate the probability of the coin landing on heads as ...To find the relative frequencies, divide each frequency by the total number of students in the sample–in this case, 20. Relative frequencies can be written as fractions, percents, or decimals. Table $\PageIndex{2}$: Frequency Table of Student Work Hours with Relative FrequenciesA conditional relative frequency is found by dividing a frequency that is not in the Total row or the Total column by the frequency’s row total or column total. A survey is conducted among school students. 50 students are randomly selected and they are asked, whether they prefer dogs, cats or other pets. The table given below … Relative frequency = event count/total count. Since we divide how many times the event occurs by the total number of events that occurred, the frequency of the event is relative to the total number of events.
