1
Q

Observations

A

made using senses; about any object or situation

2
Q

Inferences

A

generalizations developed from repeated observations

3
Q

Qualitative

A

data represented by words

4
Q

Quantitative

A

data represented by numerals

5
Q

Control

A

devised to test if the results of the experiment would occur without the impact of the independent variable

6
Q

Negative control

A

attempt to focus on certain variables to see if the desired effects occur with just those variables

7
Q

Positive control

A

check to see if your proposed independent variables will produce the effect you expect

8
Q

Hypothesis

A

statement of the relationship between the independent variables and the dependent variables; can be used to predict future experimental outcomes; simple = if/then statement

9
Q

Large sample size

A

important because unforeseen variables may not be held constant and therefore may impact results

10
Q

Repeating measures

A

repeating the experiment; important because you want to make sure the experimental results are reliable and will occur in more than one instance; the more you repeat, the better

11
Q

Reproducing the same results

A

results should be able to be obtained by others who follow your very same experimental design
