Example:
To find the average for 10,18 and 13.
We just have add the following numbers and divided them by how many numbers you added.
Solution:
10 + 18 + 13 = 41
41 / 3 = 13.67 or 14
Then the average score is 14.
Measures of central tendency are a statistical method in which you measure and gather the middlemost value of the set of parameters.
1. Median
2. Mode
<span>3. Mean, this is considered to be the average in lay man's term.<span>

The labeled point means the Amelia biked 1.5 30 miles in 1.5 hours.
This means that in 1 hour, Amelia biked 20 miles.
Her distance changed at a unit rate of 20 miles per hour, so that was her speed.
That will equal to y=4x-3 and the graph will look like a V mainly with the minimum on the point (0,-3) hope this helps\ <span />
