Descriptive Statistics For Questions on the Survey
Locate the class data for the survey question that you constructed. (You will find the data under the discussion labeled “Survey Discussion”.)
Assume the data you collected is a sample from the population of online STA2023 at BC.
Rewrite your survey question from Discussion 1. (Note that if you did not complete discussion 1, you will have to create a survey question and gather at least 30 responses via discussion, email, in-person, etc. You may want to speak with your professor about how to best handle this. You will need the quantitative data from your survey question for several discussions in this course.)
List all the class responses to your survey question in ascending order.
Find the sample mean, median, and mode for your survey responses.
Find the sample standard deviation, variance, and range for your survey responses.
Find the z-score for the largest (maximum) value in your data set. Is that value an outlier (a significantly high value)?
