Which research design would you use for the following and why:
does sleep deprivation affect driving ability?
a) correlational research
b) descriptive research
c) experimental research
explain why!

I would use the experimental research

C

Explanation

The main aim is to analyse and assess whether there is a direct link between sleep deprivation and driving ability.

With experimental research, the researcher has the ability to control and manipulate the independent variable which in this case is sleep deprivation.

In addition, other variables that may be considered to be extras can be controlled as the researcher desires.

The effect hence ability to drive can be tested under different conditions which may shed the light into the how the two variables relate.

For instance, the researcher may decide to test the driver's ability if they had 2, 5, 8 hours of sleep.

Or even add another variable alcohol or some medication.

All this information will be factored in when making a conclusion.

answer:

d. because dr. laguardia selected a widely used measure, his study generalizes to has strong external validity. external validity has limited external validity. other applications of this measure.

the widely used measure that he applied to his experiment was the benton facial recognition test. it employed on to football players and as result, only players who suffered brain concussions did not pas this test. and although it has an external validity, it is limited because it isn't general to apply to other population.

well, there are a lot of places we get information about earth from. like science classes, websites, books, newspapers, etc.
