How does time affect someone’s productivity rate?

Length of time

Volunteers will attempt to complete a puzzle in the given time to them. It will consist of unlimited time, five minutes, or  ten minutes.

# data[].attributes.body
Our control group is the subjects who will be completing the puzzle on unlimited time. They do not have a time limit therefore they could have a more completed puzzle.

We both got a list of 50 family members and asked if they would be apart of our experiment. Some potential lurking variables could be age, gender and skill. By randomizing this we can reduce this.

Randomized block design

We got 30 family members and randomly assigned them to one of three studies and we are confident that are results were due to blocking variable not being blocked

Unlimited time, 5 minutes, 10 minutes

# data[].attributes.body
30 friends and family
15 - Allison
15- Valerie

# data[].attributes.body
We separated groups into ten sections. Every group has 1 person with unlimited time, 1 person with 10 minutes, and 1 person with 5 minutes. Since we both did 15 people each (5 groups of 3) every group has a variety of different people we know.

# data[].attributes.body
At the end of the study the averages were,
Unlimited- 70%
5 minutes- 7.8%
10 minutes- 28%
So overall the unlimited time group had the most of the puzzle completed, followed by the 10 minute group, and finally the 5 minute group. The more time given the better the performance.

We did not randomize all 30 people. The results are not likely not statistical significant, because with different times some people work faster than others.

With a sample size of 30, our margin of error was at 18.2%. This is a rather high margin of error, and that means our results should be a not so good representation of the population.

# data[].attributes.body
We could replicate this study with 30 new people to compare and constrast the results. We could even find 30 people we do not know and gather their info. Another option would be to find more than thirty new people and have even more results.

# data[].attributes.body
We are not able to blind our subjects, because they will not be able to complete the puzzle if they cannot see the pieces. We also cannot do double blind because we already know who is completing the puzzle.

Our experimental units consisted of friends attending the same school and family at home. Therefore a relationship is present. Once we each explained our assignment and the experiment needing to be completed, they agreed to take part of the experiment.
