Devon wanted to investigate the impact of leading questions on the accuracy of eyewitness testimony. He recruited 10 elderly residents from a local care home where he volunteers to watch a short security camera clip of a theft in a park. Afterwards, he asked half of them: 'Did you see the man wearing the black leather jacket?' (the jacket was actually brown), and the other half: 'Did you see what the man was wearing?'.
Explain one improvement that could be made to Devon's study.
