SOC222H5 Lecture Notes - Simple Random Sample, Statistical Inference, Sampling Error
Document Summary
Just tell us the numbers spss gives, no rounding or adding zeros. 1. 34e-2 = . 0134- the number you would add on the test. E means move the deciamle point minus means move to the left. If no minus sign, or a plus sign, move decimal point to the right. This is the topic of inferential statistics we infer something about the population based on the sample. Population: a group that we are interested in ex it could be canadian cities. Research question about a particular group: sample: a set of cases selected from the population. We know the chance of any particular case being selected. (we need this for inferential statistics). Different types of random sample: simple random sample (srs)-each case has the same probability of being chosen in the population. Statistic- what we calculate from the sample is the statistic. Sample of students would be the mean age.
