1.4+1.1+1.8+1.6+1.6+2.2+1.1 = 10.8
10.8 / 7 = 1.542 rounded to the nearest tenth = 1.5 

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:

[tex]\overline{x} = \dfrac{x_1 +x_2 + ... + x_n}{n}[/tex]  where these [tex]x_i[/tex]s are data points for i = 1,2,...,n

Using the above formula to calculate the mean

[tex]\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[/tex]

(we divide by 7 since there  are 7 values)

Thus, the mean of the given data is approximately 1.5
