You can use the formula for calculating mean of ungrouped data.
The mean of the given data is 1.5
How to calculate the mean of ungrouped data?
Let there are n observation data, then their mean can be found as:
\(\overline{x} = \dfrac{x_1 +x_2 + ... + x_n}{n}\) where these \(x_i\)s are data points for i = 1,2,...,n
Using the above formula to calculate the mean
\(\overline{x} = \dfrac{ 1.4+ 1.1+ 1.8 + 1.6 +1.6 +2.2,+1.1}{7} = \dfrac{10.8}{7} \approx 1.54 \approx 1.5\)
(we divide by 7 since there are 7 values)
Thus, the mean of the given data is approximately 1.5
