A writing assignment for students in the 'introduction to statistics for the social sciences' course taught by dr. Suzanne delaney in fall 2018. The assignment focuses on understanding deviation scores, calculating standard deviation and variance, and interpreting z-scores. Students are required to identify the meaning of various symbols and concepts related to these statistical measures.

What you will learn

  • What does a z-score represent and how is it calculated for a population or a sample?
  • What is a deviation score and how is it calculated for a population and a sample?
  • Given a deviation score, how can we determine if an individual is taller or shorter than the mean and by how much?
