Answer #1

The mean is the average value of 20 observations. Hence, mean = 0.30265. (Ans).

The median is the middle most observation, i.e. median is that observation below which 50% of the observations lie and above which 50% of the observations lie. So, median = 0.308. (Ans).

The mode is the most frequent observation in the data set i.e. the observation which occurred most number of times in a dataset. Thus, mode = 0.327 (which occurred 3 times i.e. the most number of times in the dataset). (Ans).
