Length of class interval for finding Mode by the formula should be…

The following dataset represents the number of books read by 25 students in a month:
2 , 4 , 4 , 5 , 5 , 5 , 6 , 7 , 7 , 7 , 7 , 8 , 8 , 9 , 9 , 10 , 10 , 11 , 11 , 12 , 13 , 13 , 13 , 15 , 16.
Calculate the mode of the dataset.

If the mode of the following distribution is $$6\frac{1}{6}$$​, then what is the value of k?

The marks scored by 10 students are given below. 13, 20, 15, 13, 19, 12, 12, 11, 13, 10 The mode of the given data is:

Mode of distribution can be obtained from:

The mode and median of data are 36.3 and 62, respectively. What is the mean of the data?
(Use the empirical formula)

The mode and median of a dataset is 52.7 and 65, respectively. What is the mean of the dataset? (Use empirical formula, and round off your answer to one decimal place.)​

​Correct relation for the numbers 10, 7, 8, 5, 6, 8, 5, 8, 6 is:​

If the mode of the following data is 140, then what is the value of x?

What is the mode of the data given below? [Give your answer correct to 2 decimal places.]

The mean of a data is 42 and its median is 53. The mode (using empirical relation) of the data is:
