in a data set. The goal of each is to get an idea of a <strong>"typical"</strong> value in the data set. The mean is commonly used, but sometimes the median is preferred.</p> <p><strong>Range</strong> and <strong>interquartile range (IQR)</strong> both measure the<strong> "spread"</strong> in a data set. Looking at spread lets us see how much data varies. Range is a quick way to get an idea of spread. It takes longer to find the IQR, but it sometimes gives us more useful information about spread.<br></p> <p><br></p> <p><strong>First XXXX XXX (Number of times XXXXXXX by XXX police)!</XXXXXX><br></p> <p><strong>X.</strong>The arithemtic mean (XXXXXXX) XX XXX XXX XX XXX values in the XXX divided by the XXXXXX of elements in XXXX set.</p> <p>XX XXX XXXXX XXXX XXX, the XXX XX all XXX XXXXXX is 81.
