Question

Write the formula for finding mean, mode & median of the given data. ​

Answer 1

Answer:

Mean: The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Formula for finding mean: mean= Sum of the terms by Number of terms.

Median: The median is the 3.5th value in the data set meaning that it lies between the third and fourth values. Thus, the median is calculated by averaging the two middle values of 25.2 and 25.6. Use the formula below to get the average value.

Formula when the n is even: n+1st term by 2

Formula when n is odd: n-1 by 2+ n+1 by 2 divided by 2

Mode: To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

Formula of mode: L+ (fm-f1) h/ (fm-f1) + (fm-f2)
