Math 10 - Lab 1 - Graphs and Descriptive Statistics Open MINITAB file rateMP.mpj from the website. This data represents information from a sample of 700 instructors from the popular website ratemyprofessors.com. All instructors are sampled from the Foothill-De Anza Community College District. Here is a description of the data: College: Smiley: Photo: Hot: Gender: Dept: Division Num Overall Easiness Foothill or De Anza Positive Instructor has a photo Neutral Negative ✔Instructor has a chili pepper Male or Female (Reported Gender) Academic Department (example - Mathematics) Academic Division (example - PSME) Shape: Center: Number of Ratings for that faculty member Average Overall Quality Rating (1-5 scale, lowest to highest) Average Easiness Rating (1-5 scale, hardest to easiest) We are going to use Minitab to make some dot plots for this data. Specifically we are going to look at Average Overall Quality Rating and try to make some comparisons of groups. First, let's ask some questions about this data. 1. Identify the quantitative variables. 2. Identify the categorical variables. Now we are going to make some dot plots of the Average Overall Quality Rating which can be found under the GRAPHS menu command in MINTAB Spread: Unusual features: Minitab - RateMP.MPJ Eile Edit Data Calc Stat Graph Editor Tools B & fx -- ** Scatterplot...
