I just got done taking a statistics course last summer, I'll do an analysis of the results in a couple weeks (the school semester is just getting started and I'm going to be a bit busy for a couple weeks)

Preliminary Analysis:

Type: Sample (n) Sample (%) Gen Pop (%)
A+        19                27.1              35.7
A-          7                10.0                6.3
B+         8                11.4                8.5
B-    5                  7.1               1.5
O+     18    25.7             35.7
O-          9                12.9 6.6
AB+       3                  4.3               3.4

AB- 1 1.4 0.6

Our group has fewer A+ and O+ than the general population

Our group has more A-, B+, B-,O- and AB- than the general population.

I need to find my stats caluclator to figure out if these differences are statistically significant or not. I suspect the B+, B-, and O- differences are statistically significant.

Here is a comparison of the number of people who we would expect have each blood type to the number in our group who do have the blood type:

Type: We have: We expect to have: Difference:

A+ 19 25 --6
A- 7 4 +3

B+ 8 6 +2
B- 5 1 +4

O+ 18 25 --7
O- 9 5 +4

AB+ 3 2 +1
AB- 1 0.4 +1

I was told I was O. Does that mean positive or negative?

mathteacher--the letter and the + or - are 2 different things. The basic blood types are A, B, AB, and O. Then the blood is tested for the presence of the Rh factor, which is either present (+) or absent (-).

I'll add the new info to the sample group and re-analyze soon.

This is really interesting!
