Question

find the mean of the data set shown in the table below. data set c 1.74 1.71 1.07 0.8 1.13

Explanation:

Step1: Recall mean formula

The mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are data - points and $n$ is the number of data - points. Here $n = 5$, $x_1=1.74$, $x_2 = 1.71$, $x_3=1.07$, $x_4 = 0.8$, $x_5=1.13$.

Step2: Calculate the sum of data - points

$\sum_{i = 1}^{5}x_{i}=1.74 + 1.71+1.07 + 0.8+1.13=6.45$.

Step3: Calculate the mean

$\bar{x}=\frac{6.45}{5}=1.29$.

Answer:

$1.29$
