## How To Find Iqr From A Frequency Table

### IQR also is a good measure of variation in cases of skewed data distribution, and this method of calculating IQR can work for grouped data sets, so long as you use a cumulative frequency distribution to organize your data points. The interquartile range formula for grouped data is the same as with non-grouped data, with IQR being equal to the value of the first quartile subtracted from the

- Construct a frequency distribution table for dichotomous, categorical, and ordinal variables. Give an example of when the mean is a better measure of central tendency (location) than the median. Interpret the standard deviation of a continuous variable.
