Background Tutorials

  • Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered.

      What is the Median of a Data Set?

      The median is one of many measures of central tendency. Check out this tutorial to learn what the median is and how you can find it!

      What is the Mean of a Data Set?

      When you think of the mean of a data set, think of the word average. 'Mean' and 'average' are the same thing when you're talking about a set of data! This tutorial introduces you to mean and shows you how to find it!

  • Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.

      What is the Mode of a Data Set?

      Finding the mode of a set of data can help you understand the data better. This tutorial introduces you to mode and shows you how to find this helpful measure of central tendency!
