Graphical representation: Distribution curves (including normal, positive and negative skewed
- 3 things to know
- Component 2
Overview
Recall questions on Distribution curves including normal, positive skewed and negative skewed.
What you need to know
Answer each one before you reveal it.
Describe the pattern that indicates a negative correlation.
How would you recognise no correlation on a scatter diagram?
Questions from this subtopic
Each one with the model answer underneath.
- 1
Describe the pattern on a scatter diagram that indicates a positive correlation.
Model answer
The points slope upwards from bottom left to top right, showing that as one co-variable increases the other increases too.
- 2
Describe the pattern that indicates a negative correlation.
Model answer
The points slope downwards from top left to bottom right, showing that as one co-variable increases the other decreases.
- 3
How would you recognise no correlation on a scatter diagram?
Model answer
The points are scattered with no discernible upward or downward trend.
- 4
State three characteristics of a normal distribution.
Model answer
It is bell-shaped, it is symmetrical about its centre, and its tails approach but never touch the horizontal axis.
- 5
Where do the mean, median and mode lie in a normal distribution?
Model answer
All three fall at the same point, in the centre of the curve at its highest point.
- 6
Describe a positively skewed distribution.
Model answer
Most of the scores are bunched at the low end and a long tail stretches out towards the high scores on the right.
