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.
7
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.
