The mean of a dataset is the average or the expected value of the dataset

The mean of the dataset is 4/5

<h3>How to determine the mean</h3>

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:

$\bar x = \frac{\sum x}{n}$

So, we have:

$\bar x = \frac{1 \frac 13+ \frac 14+ \frac 23+ \frac 12+ 1 \frac 14}{5}$

This gives

$\bar x = \frac{4}{5}$

Hence, the mean of the dataset is 4/5
