1. What is the weighted average?

  • When you calculate the average between data
  • When you work out the fraction between the gaps of data, where each quartile is calculated
  • Where each quartile is calculated is the average is calculated between them
  • When you work out the difference between the gaps of data

2. Which statement is incorrect about counting the standard errors from the mean (6.72 mean and 7.0 intended value)?

  • Also need to know the range of values
  • Also need to know the degrees of freedom
  • Work out how may SE there are from the mean (6.72) to the sample (7.0)
  • Work out the t-statistic which is the number of SE that the difference shows

3. Which is not a characteristic of an ANOVA I within country extreme example?

  • When we can account of overall means as each country means, the country means are not significantly different, but are instead the same.
  • When we can account for all the variance by using country means instead of overall means, the country means are significantly different.
  • All the variation (this time SST=1) is within-country variation (SSE=1) and there is no between-country variation (SSM=0).

4. What does a Poisson frequency distribution graph show?

  • Unusual things
  • Usual things
  • Non existent events
  • Constant things

5. How do you calculate variability?

  • Range
  • Mode
