WebWhen the data has a high SD (e.g., SD = 25), it means that the individual data points are spread out quite a bit. On the other hand, if the data set has a smaller SD (e.g., SD = 0.3), you can infer that the data points are closer to the mean.

Interquartile Range (IQR): How to Find and Use It

WebThe formula for finding the interquartile range takes the third quartile value and subtracts the first quartile value. IQR = Q3 – Q1. Equivalently, the interquartile range is the region between the 75th and 25th percentile (75 – 25 = 50% of the data). Using the IQR formula, we need to find the values for Q3 and Q1. WebHistograms show the shape of data. Histograms show the shape of your data. The horizontal axis shows your data values, where each bar includes a range of values.
