Lab Report Assistant

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

D. If 50 subjects were not interviewed, how can the number of volunteers be justified as an adequate sample size to test the hypothesis? If 50 subjects were interviewed, how does the researcher know that this sample size is large enough to effectively test the hypothesis? The amount of people your company should survey is based on several different things. Begin by determining the number of people in your target market. Then determine how accurate you wish your data to be.

E. Why is it important NOT to tell subjects what is being determined before they clasp their hands? If you tell the subject what you are doing before they clasp their hands, they may not show you how they would normal have their hands.

F. Combine the percentages for same hand/thumb (right handed/right thumb dominant + left hand/left thumb dominant) and opposite hand/thumb (right handed/left thumb dominant + left hand/right thumb dominant) in another table like Data Table 3. The combination of same hand/thumb is 50% and the combination of opposite hand/thumb is 50%.

G. Write a paragraph that verbally presents the data summarized in Data Tables 2 and 3.
During my research I examined the clasped hands of 50 people. Out of the 50 people 10 people were right-handed with a right dominate thumb and 12 were right- handed with a left dominate thumb. I also found that 13 people were left-handed with a right dominated thumb and 15 people were left-handed with a left dominate thumb. I found that if you add same hand/thumb dominate was 50%total the right hand right thumb was 20% and the left hand left thumb was 30%. The total of right hand left thumb was 24% and the left hand right thumb was 26% which is 50%.


A. What was the hypothesis? Do the experimental data results support or refute the selected
Hypothesis? My hypothesis I made was that 60% of people would have same hand/thumb dominance. The data showed that I was wrong and only 50% of the people I examined had same hand/thumb dominance.

B. Why should the data for same handedness-thumb and different handedness-thumb be
Combined for purposes of analysis? They should be shown together to give adequate comparison.

C. Recheck all steps, evaluate the total experiment, and draw implications from the conclusions. Is the experiment valid enough to reach a conclusion? For my small sampling experiment I consider my project done.

D. How can the conclusion be supported by using statistics? You can look at the data sheet and see
the conclusion matches the data shown.

E. Are the results meaningful? The results are useful for people who are studying the hereditary traits.

F. Were enough subjects used to be conclusive? To be 100% sure of the results a larger sampling should be preformed.

G. What...
