### Objectives

• Explain why knowledge of statistics is important to laboratory scientists.
• Define terms that are associated with descriptive statistics and apply them to specific situations.
• Prepare tables and figures of data that meet the criteria specified in this unit.
• Describe "frequency distribution" and explain the advantage of presenting data in this manner.
• Given a set of data, construct a frequency table according to criteria stated in this unit.
• Given a set of data, construct both actual and relative frequency distributions that accurately represent the discrete or continuous nature of the data.
• Given a set of data, calculate its variance and standard deviation.
• Given the mean and standard deviation of a set of data in a normal distribution, find the ranges encompassing 68%, 95%, and 99% of all observations.
• Describe at least two situations in which coefficient of variation is a useful tool.
• Calculate coefficient of variation when given the mean and standard deviation of a set of data.
• Explain how coefficient of variation is used in the clinical laboratory.
