The sum of differences between sample observations and the sample mean is equal to?

Mathematics

dedylja [7]2 years ago

The standard deviation is the mean of the sum of the squared deviations between each observation and the mean. The measure of dispersion that is the easiest to compute is the interquartile range.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation implies that the values are dispersed over a wider range, a low standard deviation shows that the values tend to be close to the mean of the collection.

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Can someone give me two examples where Canadians still use the imperial system as a form of measurement?????
Nataly [62]

Remark

Acres is one example. 640 acres = a square mile. A mile is also a carryover from the imperial system. When Canada transferred over to the metric system, they found that the old system had to stay in place, otherwise all the surveying would have to be redone. There are two examples in this paragraph, but here's another as a bonus.

The Car dealerships in Canada still use the Imperial Gallon to describe how many miles per gallon you might get with the particular car you are looking at. When we bought our Honda Fit, the dealership told us we would get 50 miles / gallon,  and they were not lying. It get's a little less now but we are doing more city driving. And who knows what additives are put in the gasoline. The reason the dealerships do this is because the Imperial Gallon is larger than a US gallon. So for every gallon burned you get more miles with an imperial gallon than you do with a US gallon. That's why you learn to convert. Can't let people trick you.
