Q.1
If the range is large, the variation of the data is...
  • large
  • small
  • insignificant
  • unchanged
Q.2
The range is the same thing as this.
  • Average
  • Spread
  • Accuracy
  • Median
Q.3
If the range is large, we need to consider this.
  • Repeating the experiment many more times
  • Leaving it and working out the average
  • Changing the experiment altogether
  • Asking for more time
Q.4
What is the upper limit of the following data? 15, 18, 25, 18, 45
  • 15
  • 18
  • 25
  • 45
Q.5
Which one of the following is the range of this data? 25, 16, 18, 10, 12, 16, 17
  • 12 to 16
  • 10 to 17
  • 10 to 25

Q.6
Calculate the range of the following data. 12, 14, 16, 13, 17, 19
  • Six
  • Seven
  • Eight
  • Nine
Q.7
The range will guide us about a valid comparison between our experimental results and the control. If the ranges do not overlap, we say that there is...
  • no difference
  • a significant difference
  • a fluke
  • a chance that they may be different
Q.8
To calculate the range, we...
  • subtract the largest number from the smallest
  • subtract the smallest number from the largest
  • subtract the mean from the largest number
  • take an average
Q.9
Which is the lower limit of this range of data? 22, 14, 16, 19, 11, 28
  • 11
  • 15
  • 16
  • 17
Q.10
If there is a very wide range of data for the same experiment, we say that the data is...
