Like the range however, the inter-quartile range is a measure of dispersion that is based upon only two values from the dataset. Statistically, the standard deviation is a more powerful measure of dispersion because it takes into account every value in the dataset. The standard deviation is explored in the next section of this guide.... I'm currently teaching a yr 9 class IGCSE material where finding the IQR of ungrouped data doesn't seem to be in the syllabus. It doesn't really matter which method I teach them, I'm just interested in how it's taught in the UK.

The interquartile range is a measure of variability of data represented by the distance between the first and third quartiles of a data set. The larger the IQR, the more variability or less consistency a data … how to get the clock on desktop Do you know how to find the interquartile range of frequency data? In this clip, see how it's done using data collected about numbers of sweets. The first step is to find Q1 (lower quartile) and then Q3 (upper quartile). Next watch how a cumulative frequency curve is used to find the interquartile range of grouped frequency data. Again, it's a matter of finding the lower and upper quartiles so

## How To Find The Interquartile Range In Grouped Data

As the SIR is half of the Interquartile Range, all you need to do is find the IQR and then divide your answer by 2. Another way is to use the quartile deviation formula : Note : You might see the formula QD = 1/2(Q 3 – Q 1 ).
