What is the purpose of a t-test in psychology research?
Compares means between two groups
What is the purpose of ANOVA in psychology research?
Compares means among three or more groups
What are inferential statistics used for in psychology research?
Drawing conclusions about populations
Statistical tests are used to determine the probability that the
null hypothesis
Inferential statistics help determine if results are due to
real effects
or chance.
Match the statistical test with its purpose:
t-test ↔️ Compares means between two groups
Chi-square test ↔️ Analyses categorical data
ANOVA ↔️ Compares means among three or more groups
What is the main purpose of statistical tests in psychology research?
To make inferences about populations
Order the steps in conducting a statistical test:
1️⃣ State the null hypothesis
2️⃣ Choose the appropriate statistical test
3️⃣ Calculate the test statistic
4️⃣ Determine the p-value
5️⃣ Make a decision about the hypothesis
A t-test is used to compare the means between
two groups
Which statistical test is used to analyze categorical data?
Chi-square test
Inferential statistics help determine if sample results reflect a real effect in the
population
.
What is the primary goal of statistical tests in psychology research?
To determine statistical significance
Match the statistical test with its purpose and data type:
t-test ↔️ Compares means between two groups, Continuous
Chi-square test ↔️ Analyses categorical data, Discrete
ANOVA ↔️ Compares means among three or more groups, Continuous
Statistical tests are used to make inferences about a
population
Why are statistical tests used in psychology research?
To make inferences about populations
A t-test compares
anxiety scores
of two groups after different therapies.
What is the purpose of statistical tests in psychology research?
Analyse data, test hypotheses
A t-test is used to compare means between two
groups
Parametric tests assume data follows a
normal distribution
.
Parametric tests require homogeneous
variance
Match the statistical test with its category:
t-test ↔️ Parametric
Chi-square ↔️ Non-parametric
Steps to choose the appropriate statistical test:
1️⃣ Identify data type (categorical or continuous)
2️⃣ Determine the number of groups being compared
3️⃣ Assess sample independence (paired or independent)
4️⃣ Check data distribution (normal or non-normal)
A paired t-test is used when samples are independent.
False
Which test is recommended for non-normal continuous data with two independent groups?
Mann-Whitney U test
A chi-square test is used for analyzing
categorical
data.
What statistical test is recommended for comparing average test scores of two independent groups with normal distribution?
t-test
Which statistical test is recommended for comparing preferences for different product designs?
Chi-square test
Inferential statistics draw conclusions about a
population
based on sample data.
Statistical tests determine the probability that the null
hypothesis
is true.
Match the statistical test with its purpose:
t-test ↔️ Compares means between two groups
ANOVA ↔️ Compares means among three or more groups
Chi-square test ↔️ Analyses categorical data
What is the purpose of the ANOVA test?
Compare means among groups
What type of data does the Chi-square test analyse?
Categorical
Parametric tests are suitable for data with non-normal distribution.
False
Which non-parametric test is used to compare user preferences across categories?
Chi-square test
Non-parametric tests use ranks or
frequencies
instead of means and variances.
Match the statistical test with its recommended scenario:
t-test ↔️ Continuous data, two independent groups, normal distribution
Chi-square test ↔️ Categorical data, two or more groups, independent samples
What statistical test is recommended for comparing preferences for different product designs?
Chi-square test
