## What are Mean Median and Mode?

Mean, median and mode are all measures of valuable tendency in information. In unique methods they every inform us what value in a information set is usual or consultant of the choices facts set.

The mean is similar to the average fee of a statistics set and is discovered using a calculation. Add up all the numbers and divide by using the choices range of numbers inside the information set.

The median is the important quantity of a information set. Arrange information points from smallest to largest and find the choices central quantity. This is the choices median. If there are alternatives 2 numbers in the center, the choices median is the common of these 2 numbers.

The mode is the number in a information set that occurs maximum frequently. Count how typically every number happens within the records set. The mode is the number with the highest tally. It’s good enough if there’s a couple of mode. And if all numbers arise the same range of times there may be no mode.

## How to Find the choices Mean

The suggest is the same as the average fee in a information set.

## Mean Formula

The mean x̄ of a statistics set is the sum of all the data divided by way of the choices depend n.

## How to Find the Median

The median ( widetilde ) is the choices information fee keeping apart the top half of a records set from the choices decrease half of.

## Median Example

For the choices facts set 1, 1, 2, 5, 6, 6, nine the median is 5.

For the facts set 1, 1, 2, 6, 6, nine the choices median is 4. Take the mean of 2 and six or, (2+6)/2 = four.

## Median Formula

Ordering a records set x1 ≤ x2 ≤ x3 ≤ … ≤ xn from lowest to maximum cost, the median ( widetilde ) is the choices facts point keeping apart the choices top half of of the records values from the choices decrease half.

If the scale of the information set n is atypical the choices median is the choices fee at role p wherein

If n is even the median is the average of the choices values at positions p and p + 1 where

## How to Find the choices Mode

Mode is the value or values inside the records set that arise most often.

For the choices records set 1, 1, 2, five, 6, 6, 9 the choices mode is 1 and additionally 6.

## Interquartile Range

IQR = Q3 – Q1

Potential Outliers are values that lie above the choices Upper Fence or below the Lower Fence of the choices pattern set. Upper Fence = Q3 + 1.5 × Interquartile Range Lower Fence = Q1 − 1.5 × Interquartile Range
