Randomized/Lurking variable
We picked out 100 random people from a grade level group. Then we split them into two groups, which turns out to be 50 people in each group, for the treatment group. Potential lurking variables are the people that might normally not be used to using the writing utensil that they receive or maybe just in general they might not have the best handwriting

# data[].attributes.body
The outcome of our experiment showed that more often people with mechanical pencils wrote better when we told them that the pencil helped them write better. But the control groups showed that people wrote the same amount

# data[].attributes.body
for this experiment we need all the types of mechanical pencils, the essay paper for all the subjects, all other types of writing utensils used in the experiment such as pens and normal wood pencils. We also need to pay the people 10 dollars to take part in the experiment, that alone with 30 people is 300 dollars. Plus everything’s else, it could add up to 350 dollars.

Randomized block design
We used the random generator to choose the gender and used the generator to choose what utensil thy will be using. We had the boys use one witting utensil and the girls use another writing utensil to write with on their prompt.

Matched pair design
We matched up the people by what kind of writing utensil they prefer. Then we randomly picked one to receive the utensil they prefer and the other one to not receive that one but instead write with another utensil. This will better help us compare results at the end when we are done

Crossover design
For the crossover design we will have the students start with the mechanical pencil. Once they finish the first prompt they will switch pencils and write the next part with a regular pencil.  After we will compare the results on who had the best handwriting based on what they used to write with, we will decide on what utensil helps them write better

# data[].attributes.body
our stats don't have a huge significance. If this experiment were to be carried out the results would still show up around the same

# data[].attributes.body
The graph shows that 36 people wrote better with a mechanical pencil and 14 people did not write as good with a mechanical pencil. 32 people wrote better with they used a wooden pencil and 18 people did not write as good with a wooden pencil. The number of people are total up to 50 each which makes it 100 in total

# data[].attributes.body
We will replicate this study with 30 new people to confirm that the results are accurate and significant. We will possibly pick a new grade level group and pick a different writing utensils for them to write with

# data[].attributes.body
Our control group/Placebo would be taking half of the people in the mechanical pencil group and tell them that these pencils are guaranteed to help you write better and not say anything to the other half.

# data[].attributes.body
With our sample size of 250, our margin of error was 6.3%. This low margin of error incidents that the results we receive would be good if showing the pop

# data[].attributes.body
We are not able to blind our subjects, because each group will know what kind of pencil they are receiving to write with. There is also no double blind either because each group has 50 people in it so the group is small. We will know who is receiving what kind of pencil

# data[].attributes.body
Experiment topic
Which group has the neater handwriting/ writes better

# data[].attributes.body
Experimental units
We found 100 students (randomly chosen from a grade level) and assigned them to write a short essay/ High school students
Selection method
Choose a random group either freshman, Sophomores, juniors, or seniors. Then number people in that group and randomly choose 100 out of 250 students to participate

# data[].attributes.body
Treatments
We chose 100 random students, from whatever group was picked. There are two groups with 50 students in each. One group (15 students) will receive the mechanical pencil to write with and the other group will receive the regular pencil to write with

# data[].attributes.body
Explanatory variable
Our explanatory variable would be which treatments the units received, the mechanical or regular/wooden pencil

# data[].attributes.body
Question
What type of pencil helps you write better?

# data[].attributes.body
Response variable
After they are finished writing their essays, we have examined the handwritings from the two groups
