Tips for Comparing Two Data Sets - There are different graphical features that can be used for comparing two data sets, such as boxplots, stem plots, bar charts and so many more. However, when you are comparing two or more data sets, there are a few things you need to consider. Center: Graphically, the center of the distribution is a point where half of the observations are on both sides of the center. Spread: The spread of distribution means the variability of the data. If the observations are spread throughout a wide range, the spread is larger, and if the observation revolves around one single value, the spread is smaller. Shape: The shape determines with the means of symmetry, number of peaks, skewness etc. Unusual Features: Unusual features consist of gaps or outliers such that the data point doesn't diverge greatly from the overall nature of the data. These worksheets and lessons help students be able to compare and evaluate two seperate data sets that. This is a form of application math.

Math Skill Quizzes

I'm not a big fan of asking students to find the most correct answer, but I needed to get it in order.

  • Quiz 1 - Three class A students did not use any pencil during this month.
  • Quiz 2 - By looking at three statistics we can gauge subtle differences between two sets of data. We will start with mean and median.
  • Quiz 3 - Twenty-nine A students did not read any books during this month.
