The formula for the interquartile range (IQR) is simple: IQR = Q3 – Q1. In this formula, Q3 represents the third quartile and Q1 represents the first quartile of your data. The result reflects the spread of the middle 50% of your values, providing a robust measure of variability that ...
The IQR function computes theInterquartile Rangeof a numeric input vector. In the following article, I’ll explain intwo exampleshow to use the IQR function in R. Let’s dig in! Example 1: Compute Interquartile Range in R For the first example, I’m going to use themtcars data set. ...
Q1 (Q3) denotes the first (third) quartile. The unit of measurement is basis points. The sample period is 12/16/2017 to 12/16/2019. exchange Empty Cellmeanstd. dev.Q1medianQ3num daily obs. Bitfinex QS 0.721 0.691 0.293 0.456 0.986 695 ES 1.040 1.075 0.459 0.743 1.353 PI 0.394 0.330...
Quartiles are used to compute the interquartile range— a measure of variability around the median. The interquartile range is obtained by subtracting the first quartile from the third quartile: Q3 – Q1. It represents the range of the middle half of the data, providing insights into the over...

Furthermore, you can also use the PERCENTRANK.INC, PERCENTRANK.EXC, PERCENTILE.INC, PERCENTILE.EXC, QUARTILE.INC and QUARTILE.EXC functions to compute the relative standing of data in Excel. Method 3 – Determining Correlation and Regression 3.1 Using SLOPE, INTERCEPT, and STYEX Functions The STY...
compute the mean of the 10 values given. mean = (3+8+6+10+12+9+11+10+12+7) / 10 = 88 / 10 = 8.8 step 2: make a table with three columns, one for the x values, the second for the deviations and the third for squared deviations. as the data is not given as sample ...
