Researchers need to be extremely careful when collecting data. They must make sure that their data avoids bias, and account for any possibility of human error as well. They must also make sure that the steps taken to collect this data can be easily repeated for future replication.

The ratio of the number of cookies baked by Linus to Omar is 8 : 7. After Linus gave
away 36 cookies, Omar had twice as many cookies as Linus. How many cookies did
they bake altogether?
Answer:
120 cookies
Explanation:
Ratio of cookies baked :
Linus : Omar = 8 : 7
Let total = x
Linus = 8/(8+7) * x = 0.533333x
Omar = 0.4666666x
2(0.5333333x - 36) = 0.4666666x
1.0666666x - 72 = 0.4666666x
1.0666666x - 0.4666666x = 72
0.6x = 72
x = 72/0.6
x = 120
L / O = 8 / 7
L = (8/7)O
O 2
_______ = ____ cross-multiply
L - 36 1
2 ( L - 36) = O
2L - 72 = O divide through by 2
2 (8/7)O - 72 = 0
(16/7)O - (7/7)O = 72
(9/7)O = 72
O = (72)(7/9) = 56
L = (8/7) (56) = 64
56 + 64 = 120
