We have the Grade Point Average (GPA) scores on a four-point scale of students in Dr. Mindless’ sociology class as:

Student GPA (`x_i` )

a 2.5

b 2.0

c 3.7

d 4.0

e 3.0

f 2.2

g 2.5

h 2.1

i 3.0

j 2.5

k 2.6

l 1.6

m 2.4

Here, N = 13

`sumx_i = (2.5+2.0+3.7+4.0+3.0+2.2+2.5+2.1+3.0+2.5+2.6+1.6+2.4) = 34.1`

Mean `barX = 1/Nsumx_i`

`= 34.1/13`

`= 2.6230769`

`= 2.6` (after rounding off to the nearest tenthplace of a fraction).

**Therefore, the mean of the GPA scores obtained by the students in Dr. Mindless' sociology class is 2.6.**
