five number summary? (1 Viewer)

[insight]

Catholic trial '04
Question 27, b)ii - <i>by examining the histogram and/or polygon above, or otherwise, write down the five number summary for this set of results.</i>

huh?
i'm guessing mean, median, mode... um, standard deviation? range?

anyone want to help me out? ta.

The five number summary is:

1. Minimum
2. Lower or First Quartile (Q1)
3. Median
4. Upper or Third Quartile (Q3)
5. Maximum

That's it.

Five number summary is significant because they're the five numbers that you need to construct a box-and-whisker plot.

Hope this helps.
