Variation in peanut

weight, leaf length, forearm length and Coquina shells Lab
Purpose:
The purpose is to investigate variation in four populations, peanuts (weight), leaves (length), forearms (length) and Coquina shells, to demonstrate whether the variation is a normal distribution (makes a bell curve). Another purpose of the investigation is to learn about the effects of variation on natural selection.
Hypothesis:
If measurements of features of three populations are graphed as histograms, then those histograms will form a bell curve, because they all fit the description of normal distribution.
Results and Calculations:
- See the spreadsheet listing the group data (all of the populations except for the shells)
- See the bar graphs (all populations except for the shells)
- See spreadsheet for mean, median and mode of the forearms, leaves and peanuts.
- Observations of the Coquina shells: vary in color (white, blue, red, purple, yellow, orange, gray and brown), out of all o...
