Find the mean of the dataset { 3.4, 1.0, 5.6, 7.8, 1.2 }.

3 answers

To find the mean of a dataset, you add up all the numbers in the dataset and then divide by the total number of values in the dataset.

Mean = (3.4 + 1.0 + 5.6 + 7.8 + 1.2) / 5
Mean = 18 / 5
Mean = 3.6

So, the mean of the dataset { 3.4, 1.0, 5.6, 7.8, 1.2 } is 3.6.

Let's re-calculate the mean of the dataset { 3.4, 1.0, 5.6, 7.8, 1.2 }.

Mean = (3.4 + 1.0 + 5.6 + 7.8 + 1.2) / 5
Mean = 18 / 5
Mean = 3.6

So, the mean of the dataset { 3.4, 1.0, 5.6, 7.8, 1.2 } is indeed 3.6.
