Use the following set of data: 78, 78, 83, 85, 89, 91, 95, 98 what is the median for the set of data?

Step 1 is to sort the data from smallest to largest. This has already been done for us.

Step 2 is to cross off the outer most values until you arrive at a middle point. Check out the attached image for further details of what I mean

You'll find that 85 and 89 are tied for the middle most position, so we find the midpoint of these two values. Add them up and divide by 2

(85+89)/2 = 174/2 = 87

The median is 87

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

i would need to see the dot plot : )
