Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\text{mean}=\;\;$Unnamed gap

Advice

Mean: $\mu = \frac{1}{N}\sum\limits_{i=1}^N x_i$

Median: middle value

Mode: most common value

Standard deviation: $\sigma = \sqrt{ \frac{\sum_{i=1}^N (x_i-\mu)^2}{N}}$
