1.3 Experimental Design

Question 1

What are independent and dependent variables and where do they go?

Answer 1

Dependent (y) is the data you collect by using the Independent (x) that you change

Question 2

Importance of control groups?

Answer 2

Creates opportunity for variance

Question 3

Hypothesis format and example?

Answer 3

If… Then… Because…
(any hypothesis that makes sense)

Question 4

Give an example of usage of error bars and what do they do?

Answer 4

(any example that makes sense) Error bars show range of data; possible area where data could be true.

Question 5

Why do control groups show us variance?

Answer 5

Variance can only be deemed variance if it varies from the norm, aka the control group.
