Answer

Mean = $0.1625$ Median = $0.105$ Mode = $0.09$

Work Step by Step

Let's delete the extreme measurement of $1.07$, and invoke the descriptive statistics feature of the Data Analysis add-on, as illustrated in the screen snip below. The information we obtain is: - The mean, obtained by adding all observations and dividing with the number of observations is $0.1625.$ - The median, representing the observation under which we find $ 50\%$ of the observations, is $0.105.$ - The mode, that is, the observation appearing the most number of times in the dataset, is $0.09$.
