19. Biases
I chose to collect my data in a stratified sample, which is as follows: GT>8th Grade>5 random from each of my core classes and my enrichment class. This is unbiased because it gives everyone an equal chance of being chosen. It also gives varied input because not every one is in the Integrated 2 math class.
A few biases have occurred during this process. One of the biases being I do not have every 8th grade GT student in all of my classes. This caused bias because I did no give EVERY one a totally equal chance of being chosen, even though I was very careful through this process.

24. Observations
1: I noticed that both of the ranges are very different in the boxplots. The ranges show that the data is skewed so there are outliers.
Pt. 2: This observation is supported by observation 2 because observation 2 shows the data is skewed.
2: I also noticed the medians between the two boxplots are also very different. The medians are different because the outliers between them are different.
Pt. 2: This observation is supported by observation 1 because observation 1 shows the data is skewed.

6 (20%)

30 (100%)

27. Observations
1: I noticed that not folded had higher data points than folded because there was more people who had not folded eyelids.
Pt. 2: This is supported by observation 2 because bimodal means there are two peaks that are higher than the rest.
2: I also noticed the graph was bimodal because folded had less data which gave not folded higher peaks.
Pt. 2: This is shown by observation 1 because not folded did have higher peaks than folded.

28. Section 5: Final Analysis
Does having folded or not folded eyelids affect if people prefer TV, movies, or books?
This survey answers this question because more people with not folded eyelids prefer books and TV rather than people with folded people.
This survey did not adequately address that more people do not have folded eyelids so it is not very representative of the population.
The next step I would recommend to take is to get an even amount of people with and without folded eyelids.
