Hello, First of all, you have to order the number from least to greatest: 7,6,12,19,6,13,16,20,9
6,6,7,9,12,13,16,19,20
We see that there are total 9 numbers. Median means that the middle number, so we separate 4 numbers into two groups 6,6,7,9 13,16,19,20. Now,we see that there is only one number which is 12. As a result, the median is 12. Hope it help!
The factorial design consists of carrying out the design of equipment by testing it by modifying not the parameters one by one but by modifying several simultaneous parameters.
An experiment is termed to be a 2⁵ factorial experiment if in the experiment 5 factors are studied consecutively with each at two-level.
Thus, there are five factors and 2 levels in the experiment.
