The Measures of Central Tendency

Measures of central tendency assignment:

• Evaluate the measures of central tendency. Address the following when completing this component:
  • Which measure of central tendency is most appropriate based on the data type?
  • Are the mean, median, and mode close to the same value? If not, what does this tell you about the numbers in the set?
  • Identify any mode(s) in the data set. Is there a mode at all? Is there more than one mode?
• Calculate manually the interquartile range and the values of Q1 and Q3. (It is important to calculate this manually because the interquartile range and quartiles output from Calculator Soup might not be accurate.) Address the following when completing this component:
  • Test to see if there are any outliers in the set. If so, which number(s)?
  • Which method from Section 2.4 of the text did you first use to check for outliers?
  • Now try the other method from Section 2.4 of the text. Do you come to the same conclusion about outliers in the data set?
• Explain which descriptive statistic you think best summarizes this set of numbers and why.
• Choose three of the descriptive statistics that you feel best represent this data set. Why were they chosen?
