How do you work out the average speed of something?

Answer 1

To find the average you have to add up all the numbers that you want to average.

Then you divide the sum by the number of how many numbers you added. Then the number you have left is your average or mean.(See example for help.)

EX. 2+7+4+8+5=26

26*5=5.2

Average= 5.2

(* means divide)

What Is Standard Deviation? google_protectAndRun("render_ads.js::google_render_ad", google_handleError, google_render_ad);

To answer the question of what is standard deviation you must refer to the question raised in mean average. The mean or average have little value without some measure of the variability of the data. Standard deviation to the rescue!

The Equation

The standard deviation equation is:

It must be noted that this formula is for the sample and not for the population. If you don't know what this means, don't worry about it. For simple applications it makes little difference.

Now that you have seen the formula, let's describe what is happening in simpler terms. The formula is simply finding the average distance each data point is from the dataset mean. The squared numbers is a mathematical way of making all of the distances positive. So here is our measure of a datset: First we find the average of the data points, then we find the average of the distance each data point is from the mean or average of the data. This gives us a good beginning in describing the data within a datset.

Summary

The question of explaining standard deviation has been addressed herein. It is the average of the distance from the mean of all the data points in the dataset. To see an example of how this parameter is calculated go to Standard Deviation Calculation.

Answer 3

Add up all the prices or rates and divide it by the number of rates that you added together. The resulting answer is the average rate. Add up all the prices or rates and divide it by the number of rates that you added together. The resulting answer is the average rate.

Answer 4

Add up all of the numbers you have, and divide by the number of numbers you added. This is also called the mean.

Answer 5

add all of ur test scores (x) and then times the amount of tests you had (b) by 100 (y)

y-x= overall score.

Now we need to find the average (a)

x÷b=a

Answer 6

How many miles traveled divided by the time it took to travel.

Like if

you travel 60 miles in 60 minutes

Your average speed would be 1 mph
