Find the mean of the data
14, 14, 14, 17, 15, 16
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 15
The mean (average) of a set of data is the sum of all the observations divided by the number of observations. Repeated values, such as the three 14s here, are each counted every time they occur.
Sum of the six observations: \(14+14+14+17+15+16=90\)
Number of observations: 6
Mean \(=\) sum \(\div\) number \(=\displaystyle\frac{90}{6}=15\)
