Julie collects data on the distances travelled by snails and slugs over the duration of ten minutes. She records a summary of her findings as shown in the table below.

Compare the distances travelled by snails and slugs over the duration of ten minutes.

For average, compare medians - remember to comment with numbers, then in context.

Slugs have the higher median (9.7 > 7.1) which suggests that on average slugs move further than snails

For spread, compare interquartile ranges - again, comment with numbers, then in context.

Snails have the lower interquartile range (3.1 < 4.5) which suggests that there is less variation in the distances travelled by snails
