Question

What is the mode of Variable A? Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variable A. The vertical axis is labeled Variable B. Points are plotted at (one, eight), (two, three), (four, two), (four, six), (five, two), (six, one), (seven, three), (nine, five).

Answer 1

Variable A : 1, 2, 4, 4, 5, 6, 7, 9

Mode is the number that appears more frequently in the data set than other numbers.

1, 2, 5, 6, 7, and 9 only appeared once.
4 appeared twice.

So, the mode of the data set is 4.

Additional info:
mean = (1 + 2 + 4 + 4 + 5 + 6 + 7 + 9) / 8 = 38 / 8 = 4.75
median = (4 + 5) / 2 = 9 / 2 = 4.5
range = 9 - 1 = 8
