This link pulls up a table of Florida Crime rates between 1960 and 2000. For this week’s assignment, use the rate of violent crime rate that took place between 1985 and 2000. Answer questions 1 through 12 using the data presented in the VIOLENT CRIME RATE BETWEEN 1985 and 2000.
1. Construct a data frequency table.
2. State the mode.
3. State the median.
4. State the mean.
5. State the range.
6. State the semi-interquartile range.
7. State the standard deviation.
8. State the deviation score for the violent crime rate = 164,975.
9. State the type of data being presented and comment on how you determined this.
10. State the best measure of central tendency and the reasons why you chose that measure.
11. State the best measure of dispersion and state the reasons why you chose that measure.
12. Comment on the variability of the data.
Imagine that the 1991 violent crime rate of 157,243 was changed to 74,265 and answer the following four questions:
13. State the best measure of central tendency for the new data set and provide the reasons why you chose that measure.
14. State the best measure of dispersion for the new dataset and provide the reasons why you chose that measure.
15. Comment on the practical implications that the change in violent crime rate in 1991 from 157,243 to 74,265 had on the variability and results of the study.
For the following question, chose the best answer.
16. The median is used in social science since it
a. is easier to compute than the mean
b. describes variability especially well
c. does not use every score in a distribution
d. is less affected than the mean by extreme scores
