Math Grade 6 Quiz Measures of Center and Variation – 6.SP.A.3
In statistics, understanding the data set’s central tendency and its variability is crucial. A measure of center is a single number that describes a typical value within a data set, with common examples including the mean, median, and mode. Meanwhile, a measure of variation is a description of the spread of the data points in the data set, with common measures being range, interquartile range, and standard deviation. These measures help in summarizing and interpreting the data effectively.
