What is the mode of a distribution of scores for a variable measured by?

What is the variance of a distribution of scores for a variable measured by?

What is the mean of a distribution of scores for a variable measured by?

What is the standard deviation of a distribution of scores for a variable measured by?

Step 1

Let us take a small dataset with frequency distribution and understand all the terms with this example.

Step 2

1) Mode: Mode is the number which is having the highest frequency in the dataset.

From the above table, the highest frequency is 78. So the class respective to this is 61-71.

2) Mean: Mean is the average of all the numbers.

Calculation of mean

Step 3

3) Variance - It is the squared deviation from the center of d...
