Key term
What is the median, and how is it found?
Questions from this subtopic
Each one with the model answer underneath.
- 1
How is the mean of a set of values worked out?
Model answer
All the values are added together and the total is divided by how many there are.
- 2
What is the median, and how is it found?
Model answer
The middle value once the data is put in order, and where there is an even number of values it lies halfway between the middle two.
- 3
What does the mode of a set of readings tell you?
Model answer
Which value occurs more often than any other in that set.
- 4
What is the modal class?
Model answer
The group in a set of grouped data that holds more values than any other.
- 5
How is the range worked out, and what does it show?
Model answer
The smallest value is taken from the largest, and the answer shows the total spread of the data.
- 6
What are the lower and upper quartiles?
Model answer
The lower quartile is the value a quarter of the way through the ordered data and the upper quartile is the value three quarters of the way through.
