## What is the 25th Percentile?

The 25th percentile is a measure of position in a data set. It is the value that is greater than or equal to 25% of the data points in the set. In other words, it is the value for which 25% of the data points are lower than it.

## How to Calculate the 25th Percentile

The 25th percentile can be calculated using the formula =PERCENTILE(A2:A101,0.25). This formula assumes that the data set is placed on cell A2 to cell A101. The result of the formula is the value of the 25th percentile. In this example, the value of the 25th percentile is 20.

## Examples of Calculating the 25th Percentile

To illustrate the calculation of the 25th percentile, consider the following example. Suppose that there is a data set of house size (X) and selling price (Y). The data for house size is located in cell A2 to A16, and the data for selling price is located in cell B2 to B16. To calculate the 25th percentile, the formula =PERCENTILE(A2:A16,0.25) can be used. This formula will return the value of the 25th percentile, which in this example is 20.

## What is the Correlation Coefficient?

The correlation coefficient is a measure of the strength of the relationship between two variables. It is a number between -1 and 1. A correlation coefficient of 1 indicates a perfect positive correlation, 0 indicates no correlation, and -1 indicates a perfect negative correlation.

## How to Calculate the Correlation Coefficient

The correlation coefficient can be calculated using the formula =CORREL(A2:A16,B2:B16). This formula assumes that the data for house size is located in cell A2 to A16, and the data for selling price is located in cell B2 to B16. The result of the formula is the correlation coefficient, which will be a number between -1 and 1.
