Compute the (a) mean and (b) mode for the following set of data. Round to two decimal places. 2.5, -6.7, 3.2, -6.7,5.8

(a) Mean calculation:

Given data set: 2.5, -6.7, 3.2, -6.7, 5.8

Sum of the data:
2.5 + (-6.7) + 3.2 + (-6.7) + 5.8 = -1.9

Number of data points:
5

Mean:
\frac{-1.9}{5} = -0.38

(b) Mode calculation:

Mode is the most frequently occurring value in the data set.

The data set 2.5, -6.7, 3.2, -6.7, 5.8

The number -6.7 appears twice, more frequently than any other number in the set.

Mode:
-6.7
