Nt1310 Unit 6 Experimental Research

Answer the following question:

Define the term experiment. The term experiment is defined as a method to confirm, verify, refute, or establish the validity of a hypothesis.

When James Lind carried out his controlled experiment to find the cure for scurvy, how did he chose the six remedies that he used as treatments?

When James Lind performed his experiment, he chose the six remedies with an intention to not have an effect of the variances. He selected 12 men from the ship who suffered scurvy. He divided those 12 men into pairs and provided supplements to their basic diet for two weeks.

Based upon the work of Ronald Fisher, why are the following principles of Experimental design important?

Comparison: The purpose of comparison is to make sure

5) What is “p-hacking”? The term p-hacking is defined as a technique in which things get multiplied unless and until they obtain a desired result.

6) Describe the term confounding factors.

Confounding factors are factors that impair the accuracy or repeatability of an experiment. In other words, it is an ability to interpret results.

7) Describe/define each of the types of experiments

Controlled: An experiment that gets compared from experimental samples with control samples. Basically, they are identical to the experimental sample which is the independent variable.

Natural: Experiments that depend on the observations of the variables that are being studied. And it does not apply to the manipulations of less variables of a controlled experiments.

Field: Experiments that have a scientific control and tests a hypothesis in an artificial and highly controlled setting of a laboratory.

8) Explain how each experiment type (question 7) differs from the
