What is the Binomial Test used for?
To classify events into
two categories
View source
What question does the Binomial Test answer?
Does
sample frequency
differ from
population frequency
?
View source
What is required for observations in a Binomial Test?
Observations must be
independent
View source
What is the minimum number of observations for a Binomial Test?
10
observations
View source
How does the Binomial Test relate to the Chi Square test?
Both tests analyze
categorical data
View source
What does the Null Hypothesis (H0) specify in a Binomial Test?
Expected
proportions
of two categories
View source
What is a common expectation for proportions in a Binomial Test?
Proportions are due to chance (
50:50
)
View source
What does a p-value less than .05 indicate?
Reject the
null hypothesis
View source
What does the Binomial Test Results window show?
Counts and proportions of
categories
View source
What conclusion can be drawn if p = .004 in the coin toss example?
The coin is
biased
View source
What does a p-value greater than .05 indicate?
No
significant
difference
View source
What does the Sign Test record?
The
direction
of change
View source
What does the Sign Test compare?
Two
conditions
in a
repeated measures design
View source
What is the output of the Sign Test in JASP?
Counts and
proportions
tested against
0.5
View source
What does the Pearson Chi-square Test of Association assess?
Independence
of two categorical variables
View source
What does the Null Hypothesis (H0) state in the Chi-square Test?
Variables are
completely independent
View source
What is the alternative hypothesis (H1) in the Chi-square Test?
There is a
relationship
between variables
View source
What format is data presented in for the Chi-square Test?
Contingency tables
View source
What do expected frequencies represent in the Chi-square Test?
Predicted frequencies under the
null hypothesis
View source
How do you calculate expected frequencies?
Using
row and column totals
View source
What is the formula for the Chi-square Test of Association?
Sum of
squared
differences
divided by
expected
View source
How do you calculate the Chi-square statistic?
Sum of (
observed
-
expected
)² / expected
View source
What is the result of the Chi-square calculation for smokers and non-smokers?
Chi-square value
=
0.744
View source
What does a Chi-square value indicate?
Relationship between
observed
and
expected frequencies
View source
What behavior do males and females show regarding smoking?
Exactly the same
smoking behavior
View source
What does
f
e
f_e
f
e
represent in the Chi-square test?
Expected frequency
View source
What does
f
c
f_c
f
c
represent in the Chi-square test?
Column total
View source
What does
f
r
f_r
f
r
represent in the Chi-square test?
Row total
View source
How do you calculate expected frequencies?
Multiply total sample by
category proportion
View source
How do you calculate the Chi-square value for smokers and non-smokers?
Add up all calculated values for
categories
View source
What is the significance of the obtained Chi-square value?
It must be greater than the
critical value
View source
What is the critical value for df = 1 at alpha = 0.05?
84
View source
What does a Chi-square value of 0.744 indicate?
It is
nonsignificant
View source
How do you calculate degrees of freedom for the Chi-square test?
df
= (
R-1
) x (
C-1
)
View source
What are the degrees of freedom for a
3x2
table
?
2
View source
What is the first step to analyze data on JASP?
Create a .csv file using
Excel
View source
What variable should be defined as 'sex' in JASP?
1 = Male, 2 = Female
View source
What
should the frequency variable be named in JASP?
'freq'
View source
What is the purpose of selecting 'Frequencies >> Contingency Tables' in JASP?
To analyze the relationship between
variables
View source
What should be ticked under Statistics in JASP?
Chi-Square
,
Phi
, and
Cramer's V
