Researcher asks participants to imagine that they have been excluded from their circle of friends and then takes images of their brains using functional mag-netic resonance imaging (fmri) scanning technology. the images generated in this study would be considered data. a. experimental b

Experimental B

Explanation:

The experimental design is how to verify the hypothesis efficiently and economically. In this design, we deliberately change one or more variables concerning observe the change in response variables. The statistical design is an efficient design for the procedure.  

Experimental design determining with the hypothesis of an experiment and selecting the process factor for the study. In this design, the subjects are allocated in a different situation in an experiment. There are  two groups in which the subject are divided, the experimental group, and the control group.

There is seen the change in the experimental group rather than a control group.  

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
