![]() There's no real solution to this problem but a technique known as linear interpolation probably comes closest. As there's no such thing as “0.25 scores”, we can't precisely separate the lowest 25% from the highest 75%. Or -reversely- 75% are higher.Ī minor complication here is that 25% of N = 233 scores results in 58.25 scores. This means that 25% of our scores are lower than 811.5 milliseconds. Returns quartile 1 for the scores in cells A2 through A234 (our 233 reaction times). Quartile 1 is the 25th percentile: it is the score that separates the lowest 25% from the highest 75% of scores. We'll show you all you need to know in this Googlesheet, part of which is shown below. So what are quartiles? And how to obtain them? And how are potential outliers and extreme values defined? ![]() there's 1 low potential outlier of 239 milliseconds.the minimum reaction time (excluding potential outliers and extreme values) is around 350 milliseconds.This is the 25th percentile or quartile 1 25% of all respondents score lower than some 800 milliseconds.This is the 50th percentile (the median) or quartile 2 50% of all respondents score lower than some 975 milliseconds. ![]() This is the 75th percentile or quartile 3 75% of all respondents score lower than some 1,150 milliseconds.the maximum reaction time (excluding potential outliers and extreme values) is around 1,650 milliseconds.there's 1 high potential outlier of 1,749 milliseconds.These are reaction times between 2,551 and 2,905 milliseconds all 233 reaction times lie between 0 and 3,000 milliseconds.Some rough conclusions from this chart are that How to Make Box and Whisker Plot in Google Sheets
