SSCI 2910U Lecture Notes - Lecture 3: Normal Distribution, Quartile, Frequency Distribution
Document Summary
Slide 1: final question for 1st assignment: obtain a frequency distribution and find the normal curve. On spss go to graphs, choose histogram (after choosing variable) and choose normal curve. Slide 3: allow us to summarize the distribution without further analysis. The mode is the most common score, ex. The mode province based on population is ontario. The median divides the score in the middle, it is the middle most score. The mean is the average score, add all variables and divide by n (# of variables) In order to find true/real limits, we need to find. Interval is the difference between the upper and lower limit, ex. Slide 8: skewed the 10" (extreme score) would stand out as an outlier. Difference between statistic and parameter know for midterm! Slide 10: fd each case occurring more than once fx = multiply the x by the frequency. X age group, f number of students.
