Quantitative Analysis is 1. A logical approach to decision making 2. A rational approach to decision making 3. A scientific approach to decision making 4. All of the above

Quantitative Analysis is: 4. All of the above

Explanation:

A Quantitive Analysis is scientific approach that measures numerically, statistically, in terms of interpretating reality and decision making.

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 !
