Find the mean and median of the following data set.98, 87, 92, 79, 65, 91, 80, 92, 85, 86.
First, do you know wht mean median and mode are?
@nansie69x ?
To find the mean, take the sum of your data set (add them all up), and then divide by the number of terms in your data set (how many items there are in the data set). So, the mean will be the sum divided by the number of terms, also expressed as \[mean=\frac{98+87+92+79+65+91+80+92+85+86}{10}\]
@kittenlover731 yes i do.
I have helped you with the setup, to find the actual mean you should find the simplified fraction of what I provided.
so first, order your set of data from least to greastest
65,79,80,85,86,87,91,92,92,98
yeah , and now ?
now, you need to find the meidian
the median is 86/87
