## Other questions in this quiz

## 2. Which is not a difference between chart coloumns and histograms?

- The both contains plotting points against axis y and z
- There are no gaps between the columns in histograms but there are in column charts. This is a convention that you should follow.
- The columns in a histogram do not show sample means, but counts of data within the specified ranges. Therefore they do not have error bars.

## 3. What is known as an outlier?

- If a dataset is more than the IQR up or below
- If a dataset is less than the IQR up or below
- If a dataset is within the IQR
- If a dataset is within 25% to 75% of the IQR

## 4. Which is not a rule of thumb?

- That two means differ significantly if they are further apart than twice the larger standard error
- That two standard deviations differ significantly if each one lies outside the CI of the other
- That two means differ significantly if each mean lies outside the confidence interval of the other one.

## 5. Definition of variability

- A value that lies within the values
- All different values
- A typical value
- When cannot measure a value perfectly so automatically introduces uncertainty
