Chapter 1, Problem 7TYU
Ideally, an experimental group differs from a control group (a) only with respect to the hypothesis being tested (b) because its subjects are more reliable (c) in that it is less subject to bias (d) in that it is less vulnerable to sampling error (e) only with respect to the variable being studied

A.)dependent • variable
B.)data
C.)independent variable
A well-designed experiment will contain both positive and negative controls. Which of the following is a false statement?
Choose one from the following:
(A) a positive control experiment is missing some of the components of the experiment and should give a negative result
(B) a positive control experiment contains all of the components of an experiment and should give a positive result
(C) a negative control experiment is missing the element being tested and should give a negative result
(D) if there are multiple components of an experiment, there should be multiple negative controls
(E) if a negative control experiment give positives results, it is likely that the experiment is contaminated
State whether the following statements are true or false.
(a). A hypothesis must be testable and fasifiable.
(b). Failure to falsify a hypothesis proves that hypothesis.
(C) In the context of science, a law is general and can lead to new testable hypotheses.

- You observe that every time your neighbor, who always wears a yellow hat, walks out his front door, he gets dive bombed by a crow. From this observation, what is a testable hypothesis? What is your prediction based on your hypothesis? Please design an experiment to test this hypothesis and prediction. You must identify the independent and dependent variables, as well as at least 2 control variables, and your experiment must contain an experimental group and a control grouparrow_forwardPerson 1 Person 2 Person 3 Person 4 Person 5 Person 6 i Y; (0) 3000 2500 3000 1500 4000 5000 Y; (1) 4000 3000 2500 4000 5500 6000 D₁ 1 0 1 0 1 0 (a) Explain the "fundamental problem of causal inference."
