Answer 1

According to the stem and leaf plot, we need to look for the number that is repeated the most in a row (without counting the one that represents the row, it means the first one)

For the first row, this number is 8, it is repeated twice.

For the second, this number is 8 also, it is repeated four times.

For the third one, it is 2, repeated 3 times

For the last one, it is 5, which is repeated 3 times.

From this, the most repeated number is the 8 in the second row. In that row, each 7|8 represents 78, it means the most repeated data is 78, according to the definition of mode it is the value that appears more often in a set, then the mode of the set is 78, it is repeated four times.

Note: The "8" in the first row are not taken into account as part of the mode because they represent 68 not 78.
