If you recorded the following blood types (A+, AB-, 0+, B+, 0-, A+, A+, AB-, A+, A+, 0+), what
measure of central tendency should you report? Why?

Idon’t feel like doing the math but you need to do 2.24 divided by 7

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
