As the name suggests, interquartile range is very similar to range. The only difference is that in interquartile range interpretation, you are dealing with quartiles and not the whole dataset. Usually there are 3 quartiles: first (Q1), second.

CCSS.MATH.CONTENT.7.SP.B.4 Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. For example, decide whether the words in a chapter of a seventh-grade science book are generally longer than the words in a chapter of a fourth-grade science book.

Monthly Precipitation.
The standard deviation is an especially useful measure of variability when the distribution is normal or approximately normal (see Chapter on Normal Distributions) because the proportion of the distribution within a given number of standard deviations from the mean can be calculated. For example, 68% of the distribution is within one standard deviation of the mean and approximately 95% of the.
Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. For example, decide whether the words in a chapter of a seventh-grade science book are generally longer than the words in a chapter of a fourth-grade science book.
For example, using these six measures: 3, 9, 1, 2, 5, and 4: The quantities are then substituted into the shortcut formula to find. The variance and standard deviation are now found as before: Percentile The Nth percentile is defined as the value such that N percent of the values lie below it. So, for example, a score of 5 percent from the top score would be the 95th percentile because it is.
