Answer :
The mean of a dataset is the average or the expected value of the dataset
The mean of the dataset is 4/5
How to determine the mean
The dataset is given as: {1 1/3, 1/4, 2/3, 1/2, 1 1/4}
The mean of a dataset is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{1 \frac 13+ \frac 14+ \frac 23+ \frac 12+ 1 \frac 14}{5}[/tex]
This gives
[tex]\bar x = \frac{4}{5}[/tex]
Hence, the mean of the dataset is 4/5
