Find the value of x, if the mode of the following data is 25. 15, 20, 25, 18, 14, 15, 25, 15, 18, 16, 20. 25, 20, x, 18

Explaination: Observations Tally Marks f 14 1 1 15 III 3 16 1 1 18 III 3 20 III 3 25 III 3 Observations 15,18,20, and 25 all have the same frequency i.e., 3. For 25 be the mode of the data it should have the maximum frequency. ∴ 25 should repeat itself at least once more i.e., x should be 25
