A scientist plans to find out the cause of decrease in bird population in a location. He interviews 50 people who work in the lo
cal oil mine and 45 of them believe that the mine does not affect the birds. The scientist concludes that 90 percent of people in the location believe that the local oil mine does not cause decrease in bird population. Why is the scientist's conclusion most likely unreliable? the source of information could be biased the investigation is done by only one person bird population cannot be measured accurately the results of the investigation cannot be repeated
The scientist is unreliable since it was supposed to be collecting data on why the birds are dying not why people think they are dying. Also the data would be very biased because he is asking people if they think they are contributing to the problem.
