Question

What is the median of the data set? {100, 805, 58, 600, 450, 45, 70}

Answer 1

Arrange the data set from least to greatest:
{45, 58, 70, 100, 450, 600, 805}
Find the median by canceling out until 1 or 2 values remain in the middle of the set:
{58,70,100,450,600}
{70,100,450}
{100}
The one value left is our median
