• Make a list of the main findings

• Going through your lists, come up with • Positive aspects and • Concerns

Positive aspects of this survey:

• large enough sample, • online-so anonymous encouraging

people to answer truthfully, • clear definitions of an office worker

and a gamer.

Concerns: • Selection method not stated

• may not be random• potential for a high non-response rate-(workers too

busy)• only young people surveyed but findings

extrapolated to “9 million office workers” which may include other age-groups

• some ambiguous response options• dubious claim made: “eating lunch at a desk could

double risk of DVT”• it is staying seated that increases the risk, not

place of lunch

• There should be no ambiguity when answering a survey. This ComRes survey clearly defines an “office worker” and “a gamer” but offers the ambiguous response options: very often, fairly often, not very often in questions 9 to 12.

• The margin of error is a statistic expressing the amount of random sampling error in a survey's results. The larger the margin of error, the less confidence one should have that the poll's reported results are close to the "true" figures; that is, the figures for the whole population. Margin of error occurs whenever a population is incompletely sampled.

Margin of error when there is only 1 group =
