how to find interquartile range?

Answers

Answered by sooonnniii

The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts. The values that divide each part are called the first, second, and third quartiles; and they are denoted by Q1, Q2, and Q3, respectively.

kinnu3622: can you please give me an example?

sooonnniii: Then, from the remaining observations, compute the difference between the largest and smallest values. Forexample, consider the following numbers: 1, 3, 4, 5, 5, 6, 7, 11. After we remove observations from the lower and upper quartiles, we are left with: 4, 5, 5, 6. The interquartile range (IQR) would be 6 - 4 = 2.

Consider the set: 1, 2, 3, 4, 5, 6, 7, 8. Learn the formula. In order to find the difference between the upper and lower quartile, you'll need to subtract the 25th percentile from the 75th percentile. The formula is written as: Q3 – Q1 = IQR.
