Question 1

What are the two forms of statistical analysis?
A) Exploratory and explanatory
B) Descriptive and explanatory
C) Descriptive and inferential
D) Explanatory and inferential

Accepted Answer

The two forms of statistical analysis are descriptive (which summarizes and describes data) and inferential (which uses a sample of data to make inferences about a larger population).

Question 2

Exploring relationships between two or more variables would involve:
A) Exploratory statistics
B) Descriptive statistics
C) Inferential statistics
D) Explanatory statistics

Accepted Answer

Exploring relationships between variables requires the use of inferential statistics, which involves making inferences and drawing conclusions about populations based on samples.

Question 3

What is the alternative package to SPP that you may consider?
A) JOSP
B) JASP
C) JASE
D) JASS

Accepted Answer

There is no widely used package in the market with the name JOSP, JASE, or JASS. JASP is a popular and powerful alternative to SPP. It provides similar functionality and is regularly updated with new features and bug fixes. Moreover, JASP has an intuitive user interface and is easy to use, making it a suitable option for both beginners and experienced users.

Question 4

What is not a measure of central tendency?
A) Median
B) Mean
C) Skew
D) Mode

Accepted Answer

Skew is a measure of the shape of the distribution and how symmetrical it is, not a measure of central tendency. The other options, median, mean, and mode, are measures of central tendency.

Question 5

Parametric data is:
A) Normally distributed with the same variance for each relevant variable
B) Normally distributed with varied variance for each relevant variable
C) Not normally distributed with variable variance
D) Not normally distributed with the same variance for each variable

Accepted Answer

Parametric data is data that follows a normal distribution with the same variance for each relevant variable. This allows for the use of parametric statistical tests such as t-tests and ANOVA, which rely on the assumption of normality and equal variances.

Question 6

What is the generally accepted p-value that is used to determine significance?
A) 0.1
B) 0.01
C) 0.05
D) 0.5

Accepted Answer

The generally accepted p-value that is used to determine significance is 0.05. This means that if the p-value calculated is less than or equal to 0.05, then the results are considered statistically significant, and we reject the null hypothesis. Anything above 0.05 means the results are not statistically significant, and we fail to reject the null hypothesis.

Question 7

Which test would be used to explore the relationship between two parametric variables?
A) T-test
B) ANOVA
C) Spearman correlation
D) Pearson correlation

Accepted Answer

The Pearson correlation test is used to explore the relationship between two parametric variables. The T-test and ANOVA are used to compare means between groups, while Spearman correlation is used to explore the relationship between two non-parametric variables.

Question 8

Which test would be used to explore the relationship between two nominal variables?
A) Chi-squared
B) Pearson correlation
C) ANOVA
D) Multiple regression

Accepted Answer

Chi-squared test is used to explore the relationship between two nominal variables. Pearson correlation is used to explore the relationship between two continuous variables, ANOVA is used to compare means between three or more groups, and multiple regression is used to explore the relationship between multiple independent variables and a dependent variable.

Question 9

Which of the following is a non-parametric test?
A) ANOVA
B) Pearsons correlation
C) Independent samples t-test
D) Mann-Whitney test

Accepted Answer

The Mann-Whitney test is a non-parametric test used to compare two independent groups, making it the best choice out of the options provided. ANOVA and independent samples t-test are parametric tests used for multiple group comparisons and two group comparisons, respectively. Pearsons correlation is used to measure the linear correlation between two continuous variables.
