Introduction to SPSS

What does SPSS stand for?

• Statistical Program for Social Sciences

• Statistical Package for Social Sciences

• Statistical Process for Social Sciences

• Statistical Programming for Social Sciences

Which type of analysis is NOT a part of univariate techniques?

• Mean

• Median

• Mode

• Z Test

What is the purpose of a frequency table in SPSS?

• To compare two or more groups

• To show how frequently each value appears in a dataset

• To establish a relationship between two variables

• To conduct hypothesis testing

What is the main objective of hypothesis testing?

• To describe the relationship between dependent and independent variables

• To determine the significance of sample data in making conclusions about a population

• To compute the mean and median of a dataset

• To create charts

One-way ANOVA is used when there is

• One dependent variable and one independent variable

• One dependent variable and multiple independent variable

• No dependent variable

• Only one sample in the dataset

What is the range of the correlation coefficient (r)?

• 0 to 1

• -1 to +1

• -∞ to +∞

• 1 to 100

What does the coefficient of determination (R²) indicate in regression analysis?

• The probability of hypothesis testing

• The level of association between two categorical variables

• The proportion of variance in the dependent variable explained by independent variables

• The overall mean of a dataset

What kind of data can SPSS open?

• Only Excel spreadsheets

• Only plain text files

• Only relational databases

• Excel spreadsheets, plain text files, relational databases, Stata, and SAS

In SPSS, which menu option is used to perform One-Way ANOVA?

• Analyze > Descriptive Statistics > Frequencies

• Analyze > Compare Means > One-Way ANOVA

• Analyze > Correlation > One-Way ANOVA

• Analyze > Descriptive Statistics > One-Way ANOVA

What is the purpose of post hoc tests in ANOVA?

• To determine whether there is a significant difference between means

• To analyze frequency distributions

• To compare independent and dependent variables

• To check normality of data
