Question 1 of 9

1

Inferential statistics are used to show how likely it is that an effect or difference, as seen, for example, between conditions of an experiment, has arisen by ?_

Select one of the following:

chance.
me
data
graphs
the man behind you
probability
extraneous variables

Explanation

Question 2 of 9

1

If an effect is highly unlikely to have arisen by chance, then psychologists find that is more _?____ significant, and record a positive result.

Select one of the following:

statistically
qualitatively
quantitatively
inferentially
generally

Explanation

Question 3 of 9

1

For example, if examining reaction time with and without alcohol, psychologists may have a _? predicting that reaction time with alcohol will be slower than reaction tie without alcohol. If people's reaction times with and without alcohol are very similar, it's likely that alcohol does not make a significant _?___ to reaction time.

Select one or more of the following:

hypothesis
difference
change
trouble
effect
affect
string

Explanation

Question 4 of 9

1

However, if reaction time with alcohol is considerably longer than without alcohol, it is likely that this effect has not occurred by chance. To test this, _?_ tests are used.

Select one or more of the following:

inferential
predictability
probability
reliability
urine

Explanation

Question 5 of 9

1

____?_ statistics allow us to draw conclusions, such as using a ? to see that one group of participants does better on a task than another group. But inferential statistics tell us whether or not this difference is significant.

Select one or more of the following:

descriptive
graph
table
inferential
quantitative
data
valid
chart
zimmerframe

Explanation

Question 6 of 9

1

When completing an inferential test, both a null and __?_ hypothesis are needed.

Select one or more of the following:

alternative
non-directional
directional
sham
other

Explanation

Question 7 of 9

1

Inferential tests can also assess whether there is a significant _?_ between two variables.

Select one or more of the following:

correlation
other
pattern
difference
thingie

Explanation

Question 8 of 9

1

What is meant by 'chance in inferential statistics is linked to __?_. Psychologists, can never be totally sure that an observed effect was not due to chance, but it is possible to state how certain you can be. In general, psychologists use a ? level of p is less than or equal to _?_. This means that there is less than or equal to a_?___ possibility that the results occurred by chance.

Select one or more of the following:

significance
probability
0.05
5%
0.02
0.01
1%
1 in 5
difference
credibility

Explanation

Question 9 of 9

1

If psychologists want to be more ?, they will use p is less than or equal to 0.01 or 0.001, rather than p is less than or equal to 0.05. In these cases, the probability that the observed effect occurred by chance are ? respectively. The chosen value of 'p' is called the ?_.

Select one or more of the following:

certain
1% and 0.1%
10% and 1%
0.1% and 1%
significance level
chance
possibility level
effectivity scale
