The totals are in cells B31 and C31 respectively Which of the following gives the mean petrol consumption in miles per litre
=C31/B31

Which of the following is not a characteristic of quota sampling?
The researcher chooses who to approach and so might bias the sample
Those who are available to be surveyed in public places are unlikely to constitute a representative sample
The random selection of units makes it possible to calculate the standard error
It is a relatively fast and cheap way of finding out about public opinions
Snowball sampling can help the researcher to:

None of the above
The standard error is a statistical measure of :
The normal distribution of scores around the sample mean
The extent to which a sample mean is likely to differ from the population mean

All of the above
A simple random sample is one in which:
From a random starting point, every nth unit from the sampling frame is selected
