10. Variability (Ghost Blaster)
 Most people scored between 15 and 24, but
some got a lot lower than that.
 There is a gap between negative 35 and
negative 9.
 There are lots of clusters between 15 and 35.

11. Variability (Stop Watch)
 There are gaps between 24.31 and 27.11, and
27.11 and 29.
 There are clusters in 29-30, because that is
when most people stopped.
 There are some outliers, 24.31, and 27.11.
Most people stopped at a higher time.
 Only a few people stopped over 30.00.

12. Variability (Hand Slaps)
 The mean, median, and mode are all in one
place, 2-3. That is what most people scored.
 The min is 0 and max is 7, but neither are
outliers because there are no gaps in the
data.
 The cluster are2-3 also, because that is the
normal amount of slaps that someone got.

13. Typical Conclusions
 In Ghost Blaster, the
mean, median, mode, and clusters are
between 15 and 30. So, the typical student
scored between 15 and 30.
 On the Stop Watch, the
mean, median, mode, and clusters are
around 30, because we were trying to get
exactly 30. So, the typical student stopped it
at about 30.00.
 In Hand Slaps, the mean, median, mode, and
clusters are between 1 and 3. So, the typical
student scored between 1 and 3.

14. Who’s Faster?
As you can see from the chart below, the girls have a
mean and median which is higher, but is also closer
to 30, which was the target. Since the girls got
closer, they reacted faster.
