## How do you analyze coefficient of variation?

The coefficient of variation (CV) is the ratio of the standard deviation to the mean. The higher the coefficient of variation, the greater the level of dispersion around the mean. It is generally expressed as a percentage.

## What is the formula of coefficient of quartile deviation?

Quartile Deviation =(Q3 – Q1) / 2 While the coefficient of quartile deviation is used to compare the variation between two data sets .

How is QD calculated?

Q.D. = Q3 – Q1 / 2 So, to calculate Quartile deviation, you need to first find out Q1, then the second step is to find Q3 and then make a difference of both, and the final step is to divide by 2. This is one of the best methods of dispersion for open-ended data.

How do you find the 1st quartile?

The first quartile, denoted by Q1 , is the median of the lower half of the data set. This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1 . The third quartile, denoted by Q3 , is the median of the upper half of the data set.

### How do you calculate q1 q2 and q3?

Quartile Formula: Formula for Lower quartile (Q1) = N + 1 multiplied by (1) divided by (4) Formula for Middle quartile (Q2) = N + 1 multiplied by (2) divided by (4) Formula for Upper quartile (Q3) = N + 1 multiplied by (3) divided by (4)

### How do you find the 1st quartile in Excel?

Quartile Function ExcelType your data into a single column. For example, type your data into cells A1 to A10.Click an empty cell somewhere on the sheet. For example, click cell B1.Type “=QUARTILE(A1:A10,1)” and then press “Enter”. This finds the first quartile. To find the third quartile, type “=QUARTILE(A1:A10,3)”.

#### How do you find the upper and lower quartile in Excel?

Click on cell “B2” and enter the following formula, without quotes: “=QUARTILE. EXC(A:A,1)”. This will give you the first quartile. Enter the same formula into cell “B3,” except change “1” to “2” and you will get the second quartile, or median.

#### How do you find upper and lower quartile?

AnswersThe values in ascending order are: Median = (12th + first) ÷ 2. Range = difference between the highest and lowest values. = 57 – 1. Lower quartile = value of middle of first half of data Q1 = the median of 1, 11, 15, 19, 20, 24. Upper quartile = value of middle of second half of data Q3 Interquartile range = Q3–Q1
