Science Inquiry

Question 1

control group

Answer 1

a comparison group that is as similar as possible to experimental group, except for the variable being tested;
- independent variable is absent or unchanged

Question 2

controlled variable

Answer 2

variable that is controlled and kept constant during experiment

Question 3

dependent variable

Answer 3

variable that changes as a result of changes to the independent variable

Question 4

extrapolation

Answer 4

extension beyod the measured range of data to predict or construct new data has not been measured

Question 5

hypothesis

Answer 5

scientific statement based on the variable information that can be tested by experimentation

Question 6

independent variable

Answer 6

variable intentionally varied to see an outcome will be for another variable

Question 7

interpolation

Answer 7

predicting or constructing a new data point that has not been measured but is within the range of measured data

Question 8

mean

Answer 8

average set of values

Question 9

measurement error

Answer 9

difference between measurement result and currently accepted standard value

Question 10

median

Answer 10

central value of data set, if even number take average of 2 central values

Question 11

outlier

Answer 11

data point that does not fit in pattern shown by other measured data points

Question 12

Answer 12

data measured from yourself

Question 13

measurement with descriptive or non-numerical values

Question 14

quantitative data

Answer 14

measurement with numberical values

Question 15

Question 16

refinement

Answer 16

methods that alleviate to reduce harm or distress on test animals; to enhance the animal’s wellbeing

Question 17

reduction

Answer 17

using only minimum number of animals in research to satisfy statistical requirements

Question 18

reliability

Answer 18

the degree to which an instrument/protocol/procedure is able to repeatedly measure and achieve similar results for the same population

Question 19

replacement

Answer 19

substitution of insentient materials or animals or lower sentience for conscious living animals
or use of animal models

Question 20

secondary data

Answer 20

data that has been collected by someone else

Question 21

theory

Answer 21

collection of models and concepts that explain specific systems
- allow predictions to be made and hence can be proved false

validity

Answer 22

the extent to which tests (variables were controlled in) measure what was intended that are accurate

Answer 23

likely explanation of an observation

Question 24

observation

Answer 24

using all your senses to notice things around you

Question 25

variable

Answer 25

something that can affect the results of an experiment
