Evaluate data and sources of information when using scientific information to make decisions. Use reason and logic to evaluate information, perceive patterns, identify relationships, formulate questions, pose problems, make and test conjectures, and pursue ideas that lead to further understanding and deeper insights. Organize and display data from statistical investigations using frequency distributions, percentiles, quartiles, deciles, line of best fit or matrices. However, the coefficient of determination changes from 0.52 to 0.92 just because one point has been changed. We wanted to see if air temperature affects relative humidity.
Relative humidity is a percent.
It is calculated by the taking the ratio of the amount of moisture in the air divided by the amount of moisture the air can hold. The hypothesis is that warm air can hold more moisture than cold air. We got temperature and relative humidity information from a weather information site on the Internet. We collected this data for one day to try to make sure that other weather conditions were about the same over our 12-hour period. We assumed that the amount of water in the air was approximately constant over this 12-hour period.
