Suppose that the good professor had instead taken a randomized and enumerated list of all students in the UC system and randomly selected a starting point on that list (say, student number 21,058). He then selects that student for inclusion in the sample, and every 25th student thereafter (cycling back through students 1-21,057). What sampling design did he use

Systematic sampling

Step-by-step explanation:

Here , Professor had taken a randomized and enumerated list of all students in the UC system and randomly selected a starting point on that list.

He then selects that student for inclusion in the sample, and every 25th student thereafter.

That clearly shows that he is following the systematic sampling technique, where k= 25.

Hence, the sampling design he used = systematic sampling

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
