Lab 1 – Worksheet B – Hand length vs. Height Hypothesis
This Word document has been designed to allow you to add or remove space to
accommodate your responses. Answers to questions should be a minimum of two
complete sentences in length. Your responses must be in your own words.
Step 1 – Observations:
1.
Observe people while going about your daily life, pay particular attention to height
and hand length. Then, describe your observations about the relationship between
people's hand and foot length.
People's hand tend to have a direct ratio to their height. Taller people often have longer
hands, and shorter individuals have shorter hands.
Step 2 – Facts:
2.
List the information and data you need to carry out an experiment about the
relationship between hand length and height. Describe how you will take
measurements.
I will need data about a person's hand length and height for this experiment. I will
ask a person their height and use a ruler to measure their hand length from the
middle finger to the wrist.
Step 3 – Establishing a Hypothesis:
3.
Based on your observations, write a hypothesis that relates a person's height to his
or her hand size.
A person's hand length and height are directly proportional.
A person with a
longer hand will be higher than the person with the smaller hand.
Step 4 – Gathering Data
Gather data by asking 10 or more random people (research participants) for their height
and ask to measure the length of their hand, from the middle finger to the wrist.

Step 5 – Evaluating the Hypothesis Based Upon the Data
4.
Based on the results of your graph, does the data support your hypothesis? Explain.
The data does partially support my hypothesis. There is an obvious trend showing
that a higher person will tend to have a longer hand length in the data.
5.
Based on your results, what would modify what you would change if you did the
experiment again? Revise your hypothesis.

Lab 1 – Worksheet B – Hand length vs. Height Hypothesis
I will have to consider other factors that contribute to a person's height. There is a
direct relation between a person’s hand length and their height, but there are other
factors that affect the ratio between them.
6.
Not every experiment goes according to plan, what were some problems or unusual
observations made during the experiment?
There are abnormal cases like a person still having significantly bigger or smaller hands
than other people with similar height. Even when it still somewhat follows the trend
but not quite right.
7.
Describe how this experiment could be further expanded, i.e. what else could be
done to improve the experiment?
We have to consider other variables. First, we have gender, female tends to have
smaller hands than male. Next is ethnicity, people from one ethnicity most likely will
have a different ratio between hand length and height than others.
8.
How do you think the results of the experiment would be different if you took
measurements for a hundred people? What about 1,000,000 people?
We definitely will have a more precise result if we took measurements on a bigger
size. A hundred people might not be so different from ten people, but with 1,000,000
the result will come out significantly more precise because we can cover a large
group of people.
