How To Calculate The Midrange

Statistics Definitions > Midrange

What is the Midrange?

The midrange is a type of average, or mean. Electronic gadgets are sometimes classified as "midrange", meaning they're in the middle-cost subclass.

The formula to discover the midrange = (high + depression) / 2.

Sample problem: Electric current cell phone prices in a mobile phone store range from $40 (the cheapest) to $550 (the most expensive). Find the midrange.
Pace ane: Add the lowest value to the highest: $550 + $forty = $590.
Step two: Divide Stride 1 by two: $590 / 2 = $295.
The mid priced phones would be priced at around $295.

Departure Between a Midrange and a Range.

The range is a measure of spread. In the cell phone example, the range would exist: $550 – $40 = $510. The range can also hateful the entire range of numbers—for example, information technology could be written equally $forty to $550. The mid-range takes it a footstep farther and divides the range past two to find a type of boilerplate.

Difference Between a Midrange and the Interquartile Range.

The midrange is often confused with the interquartile range (IQR), sometimes called the "middle fifty". They actually mean very different things. The mid-range is a type of hateful, while the interquartile range is talking about a chunk of data in the middle of a information set.

For example, when the weather service reports that a "mean daily temperature" is 77 degrees, they are talking about the mid-range. They got that number by taking the sum of the high daily temperature and the low daily temperature and dividing by 2. Let'due south say the recorded daily temperatures were:
55, 65, 67, 69, 70, fourscore, 81, 87, 90
High = xc
Low = 55
Mid = (90 + 55) / ii = 154 / 2 = 77.

The IQR for this data set is the 25th percentile subtracted from the 75th percentile:
25th Percentile: 66
75th Percentile: 84
Interquartile Range: 84 – 66 = 18
