What is continuous data? - CORRECT ANSWER - Data that can take any
value on a given range. e.g. height, weight, length etc.
What is discrete data? - CORRECT ANSWER - Data that can only take
specific values. e.g. shoe size, number of people, colour.
What is a quantitative variable? - CORRECT ANSWER - A variable
associated with numerical observations.
What is a qualitative variable? - CORRECT ANSWER - A variable associated
with non-numerical observations
What is the formula for Mean from a Frequency Table? - CORRECT
ANSWER -
What are the steps in calculating the Mean from a Frequency Table? -
CORRECT ANSWER - 1) Add a column for midpoints, x.
2) Multiply the frequencies by midpoints and add to the fx column.
3) Add up the fx column.
4) Divide the sum of the fx column by the total frequency.
How is the Interquartile Range calculated? - CORRECT ANSWER - Upper
Quartile - Lower Quartile
What is the formula for Standard Deviation for a list of numbers? - CORRECT
ANSWER -
, What are the steps in calculating the Standard Deviation for a list of numbers? -
CORRECT ANSWER - 1. Add up all the values of x, this is ∑x
2. Square all the values and add up, this is ∑x²
3. Count the number of values, this is n.
4. Substitute all these values into the formula.
What is the formula for Standard Deviation for a Frequency Table? -
CORRECT ANSWER -
What are the steps in calculating the Standard Deviation from a Frequency
Table? - CORRECT ANSWER - 1. Calculate the mean.
2. Square all the midpoints and multiply by the frequency. Add up all these
values, this is ∑ƒx².
3. Divide ∑ƒx² by the total frequency and subtract the mean squared.
4. Square root.
