Answer:
affect the validity and the bias
Step-by-step explanation:
Research bias, which can also be referred to as experimenter bias, is a deliberate attempt by a researcher who is carrying out an experiment to influence the research results, so that he/she can obtain a predetermined outcome. He can do this by deliberately tailoring the method of data collection to such methods as suit the achievement of such predetermined outcome. This is called data collection bias in research. Hence the process of data collection affects the bias of a study.
A study is valid if it truly achieves its aim. Validity refers to how correct or incorrect the results of a scientific study is. Validity of a study often depends on the method of data collection. If the correct method of data collection was used during the study, then its results will be valid.
Answer:
Your table might look something like this:
The dads steps:
3
6
9
12
15
18
Sons steps:
5
10
15
20
25
30
You can notice the pattern. If dad walks 3 steps, son walks 5. If dad walks another 3, son walks another 5. And so on. This means dad walks 12 steps when the sin walks 20 steps.
Step-by-step explanation:
The ratio is 3:5. This means dad wlaks 3 steps so son must walk 5 steps basically. So.......... You can now create the table. Y I just have to multiply or divide each side ( of the colon:) so. Whatever you do to one side, you do to the other side. If you x3 on one side, you do it to other. Same goes for division. In the 'table' I did above, I x2 to get 6 and 10. Then I took the 3 and the 5 again and timsed those by 3. You can also change the 6 and the 10. So:
3:5
Then x2
6:10
Then I take the top layer (you can either choose to change the top layer, or layer above as long as you do the same thing to each side. Remember, only x and ÷. No + or-.) and I x3
9:15
Then I could take 9 and 15 and x5
45:75
It's crazy that all these. Ratios mena the same thing! 45 steps from dad would take the son 75 steps. You can also divide the last ratio of 45:75 to find the one you started with, 3:5.
So you get the idea.
It is probably best to do what I did in the table in the answer part because I did a pattern. Take the top layer, and x2, then x3, then x4, ect. Rather then doing random things.
