Document Summary
Understand basic de nitions related to the process of statistics. Parameter: a number that is calculated by surveying the entire population. Statistic: a number that comes from surveying the sample. Raw data: a list of the data set. At elon 60% of the students are female. In our class, 73% of the students are female. At elon 11% of the students are from nj. We sample 5 students in our class: 4. 5, 10, 6, 9, 8. Raw data: yes, 4. 5, 10, 6, 9, 8. Problems with study: small sample size, estimated hours of sleep, lack of variability in sample, was not a random sample (people volunteering answers will always skew data) If you survey the entire population you are able to get a parameter (only way to calculate a parameter is to survey the entire population) A census does not produce a statistic, they produce a parameter.
