Questions 1 – 6 refer to the following data set. 0, 1, 7, 8, 4, 6, 7, 5, 6, 4, 5, 8, -15, 4, 3, 2 1. The mode is A 3.4 B 4 C 4.5 D 5.5 2. The mean is closest to A 3.4 B 4 C 4.5 D 5.5 3. The median is A 3.4 B 4 C 4.5 D 3 4. The range is A 2 B 0 - 2 C 23 D -15 - 8 5. The data type is A discrete B continuous C categorical D nominal 6. If the data represents the number of times 16 surveyed people exceeded their mobile phone data usage over a period, the score -15 would mean that A One of the people surveyed lied and we cannot use any data from the survey because we don’t know who it was. B It’s a mistake because you can’t have a negative number of times you’ve exceeded the data. Just make a note of it and use the data for the remaining 15 you have. C It’s a mistake because you can’t have a negative number of times you’ve exceeded the data.That score needs to be changed to +15. D It’s not a mistake. The person probably meant that she didn’t use any data 15 times.
