Suppose you carried out a survey and collected the data of height as shown below.Now, you want to calculate the frequency of height in the following intervals:< 155155-160160-165165-170> 170The intervals {155, 160, 165, 170} are given in E4:E7.To calculate the frequency, first select five consecutive cells (4 + 1).Then, enter the following syntax:= FREQUENCY (B4:B14, E4:E7)and press CTRL + Shift + Enter.It will return the frequency. After incrementing value present at index (A[i] % n) for each element A[i] by n, the array becomes {2, 8, 13, 12, 1}. But, the result displayed is not accurate as in the statistical formulas where the array is used in the calculation, the result tends to deviate from being exact. Now the resultant answer is complete. Now take one element from the original array, a and calculate k=element value - min. Step-by-Step Examples.
