An experimenter studies vision in low light by having participants sit in a darkened room for

either 5, 15, or 25 minutes and then testing their

ability to correctly identify 20 objects. (a) What is

the independent variable here? (b) What are the

conditions? (c) What is the dependent variable?

(d) You would use the scores from which variable

to create a frequency distribution?

Independent variable- time spent in the dark room

Dependent variable - number of objects correctly identified

Conditions of the experiment- low light environment and lighted environments

Scores from the independent variable are used to construct the frequency distribution

Step-by-step explanation:

The independent variable is the factor that is being manipulated in an experiment and this time it is the time spent in a darkened room.

The dependent variable is the response variable, in this case, the number of objects correctly identified.

The experimental conditions involved bringing people from a lighted area into a darkened room.

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
