The study investigated the relationship between height and jumping ability in 20 children ages 9-10. Participants' heights and furthest jump distances were measured and recorded. On average, participants could jump 22cm further than their height. While taller children tended to jump further, some variability existed, likely due to individual jumping ability. Limitations included a small sample size and difficulties with measurement procedures. Extending the study to other ages could provide more insights into the relationship between height and jumping ability.

1. Length Investigation
Aim:
To investigate the relationship between a people’s height and how far she
or he can jump.
Hypothesis:
I predict that the taller person can jump longer that the shorter person.
Materials:
Measuring tapes
20 people
Clipboard
Paper
Pencil/erasers
Method:
1. Put a string of tape on the wall.
2. Make it as long at the wall.
3. Then, take a person and place their back on the wall.
4. No bending knees or tiptoes.
5. Take a ruler a place it on top of the head.
6. Take a pencil and draw a line where the ruler is (which is on the
tape).
7. Make a tag right next to the line and right the person’s name.
8. Then, measure from the line down to the ground.
9. Do not slant the measure tape please.
10. Record the measurement on the piece of paper.
11. Repeat the measurements twenty times.
12. Take a person outside.
13. Place the person at racing line.
14. Ask the person to jump from the line, from a standing position.
15. Measure the person feet’sfrom the tip and back to the starting line.
16. Record the measurement on the same piece of paper.
17. Repeat this measurement twenty times.

Conclusion:
People can jump further than their height. On average, people can jump
22cm further than their height.
The graph shows the relationship of height and jump. It is mostly linear.
That means that taller people tend to jumper further than shorter people.
But, some tall people jumped a short distance and some short people
jumped a long distance. This depends on how good they are at jumping.
Discussion:
The sample size was 20 people but we could have measured more people
to be sure of the relationship between height and jump. It was
difficult measuring the person’s height because sometimes the measuring
tape would slant and sometimes it got bent. Also sometimes people’s
shoes had heels and had to be taken off. Then, sometimes people had to
wear shoes and some couldn’t. On the other hand, it wasn’t so difficult to
measure the jump but we had some difficulties. One part was difficult
because we had to take twenty people outside and then they wore jackets
and they couldn’t jump well with heavy jackets.
The data was for the investigation was for 9 to 10 years old. We would
have to start over to do young children and adults but it would be
interesting to do it. Then thatwill help us to understand the relationship
between height and jump in people of all ages.
