Aresearcher tested a treatment and a control group in an experiment with 15 subjects in each group. although a t-test indicated the means for the dependent variable were not statistically different, the effect size for the independent variable was .50. a power analysis revealed that the power of the study was .26. this means that
a) the difference between means in the experiment was 26
b) the value of the t-statistics is 0.13(0.50*0.26)
c) a statistically significant outcome would be obtained in approximately 1 in 4 attempts with this sample size and effect size
d) the probability of obtaining a statistically significant difference for this experiment is .74(1-.26)

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 !

hello,

your answer is ready

i believe its either the first or third option but i'm leaning more towards the third option:

the first excerpt makes a logical appeal, while the second excerpt makes an emotional appeal.
