Question
The drinks manufacturer wants to advertise the effect of the drink on reaction time.The manufacture needs to confirm the effect on reaction time by improving theinvestigation.Give two improvements the manufacturer would need to make to this investigation
Solution
-
Control Variables: The manufacturer needs to ensure that all other variables that could affect reaction time are controlled. This includes factors like age, health status, time of day, and whether the participant is a regular consumer of the drink or not. By controlling these variables, the manufacturer can be more confident that any changes in reaction time are due to the drink and not some other factor.
-
Larger Sample Size: The manufacturer should also increase the sample size of the investigation. The larger the sample size, the more reliable the results will be and the easier it will be to generalize the results to the larger population. This also helps to reduce the impact of outliers or unusual results.
These two improvements will help to increase the validity and reliability of the investigation, providing more accurate information about the effect of the drink on reaction time.
