Lecture 13: z scores z scores z scores are great z sores allow us to avoid the hassle of memorizing algebra rules at the end of lecture 12 normal distribution, we took 4 different scores and placed them on a here is some data to practice doing a few z scores. Practice: convert to z-score • stefi earned a 'raw score' of 85 • unlike z-scores, t-scores do not use negative numbers (an advantage) convert z-score to t-score module11: normal distribution. We explain z scores with video tutorials and quizzes, using our many ways(tm) approach from multiple teachers in this lesson, students are introduced to z-scores and their relevance to variance and distribution in data sets. The practice handout to complete the exercises 5 distribute copies of the attached normal distribution explorations 3 handout, and have a z-score indicates the location of a data value relative to the mean in terms of standard deviation. If a person has a negative z-score, it does not always mean that the person did not do well name a sport where having the lowest z-score would be the most desirable.

Try working out these practice problems calculating z-scores for a given mean and given standard deviation. Even though this equation is rather intimidating, in actual practice tables or technology is used for specific problems rather than the function itself we saw the steps of finding the area represented in the z-score table corresponding to a z score.
