Answer

Mode is the highest frequency data value in the given data set

Here, we can see that the stem 7 has three leaves with 1

stem 13 has two different set of leaves which contain 3 leaves with 2 and three leaves with 6

So, we can say that the given data set is trimodal, i.e. three modes

71, 132 and 136

therefore, required modal anxiety levels are 71,132 and 136
