Answer

Since there are 16 elements, divide their sum by 16 to get the mean:

$(1+ 2+ 3+ 3+ 4+ 4+ 4+ 5+ 5+ 6+ 6+ 6+ 6+ 7+ 9+ 10) \div 16 = 81 \div 16 = 5.0625$

Question

Give the median of the following eight scores:

Tap to reveal answer

Answer

Arrange the scores from least to greatest.

$\left \{ 61, 67, 68, 72, 73, 76, 80, 90 \right \}$

There are an even number (eight) of scores, so the median is the arithmetic mean of the middle two scores, 72 and 73. This makes the median

$\frac{72 + 73}{2} = 72.5$
