7

Question 2

what are the key features of science

Answer 2

1) hypothesis testing
2) empirical evidence
3) falsifiability
4) replicability
5) control
6) objectivity
7) theory construction

Question 3

how do we test the hypothesis

Answer 3

using the scientific process

Question 4

what do researchers do while using scientific processes

Answer 4

researchers collect results, then they interpret the results to reach a conclusion

Question 5

what is hypothesis testing

Answer 5

the key feature of science is hypothesis testing, which means we use the scientific process to test the hypothesis

Question 6

if hypothesis testing leads to results that don’t support the hypothesis, researchers need to…

Answer 6

adjust their hypothesis

Question 7

what is the first feature of science

Answer 7

hypothesis testing

Question 8

what is empirical evidence

Answer 8

information collected through direct observations

Question 9

what is falsifiability

Answer 9

to test an hypothesis it must be possible to prove it false

Question 10

what does it mean if an hypothesis isn’t falsifiable

Answer 10

it’s not scientific

Question 11

what does replicating a study mean

Answer 11

repeating the study to re-test the hypothesis

Question 12

if a result is replicated this means

Answer 12

a replicated study had the same results

Question 13

what is a falsifiable hypothesis

Answer 13

is one that can be proven false, using the scientific process

Question 14

what does science involve

Answer 14

science involves comparing an experimental group to a control group

Question 15

what is a control group

Answer 15

a level of the IV which is not manipulated by the researcher

Question 16

what is an experimental group

Answer 16

the level of the Iv where the researcher does manipulate the iv

Question 17

why must experiments have a control group

Answer 17

we need something to compare to the experimental group

Question 18

what happens when a experimenter stops extraneous variables from affecting their results

Answer 18

the researcher has controlled the extraneous variables

Question 19

what are extraneous variables

Answer 19

something other than what we are studying which affects the DV

Question 20

What is a confounding variable

Answer 20

extraneous variable varies according to the level of the IV.

Question 21

how is an extraneous variable also a confounding variable

Answer 21

it varies according to the level of the IV

Question 22

what does objectivity mean

Answer 22

a researcher must not let personal bias affect the way they carry out the experiment

Question 23

what is meant by control in the context of scientific research

Answer 23

Control in an experiment refers to whether the experiment is using a control group, and whether extraneous variables have been controlled.

Question 24

what is meant by falsifiability as a feature of science

Answer 24

Falsifiability is when the hypothesis we are testing can be proved false.
