Answer to Question 1

Answers will vary. Possible answer: If the data set is very large, it may be hard to get a picture of the data from the original data. Organized data summarizes the data and may enable the researcher to see patterns and trends in the data. Since the organized data is only a summary of the data and does not give the exact data values, it may sometimes be preferable to use the original data, for example to find the exact value for the average.

Answer to Question 2
