This book teaches how to use IBM SPSS Statistics, a popular statistical software package. It covers the same procedures found in versions 19 through 22, making it relevant to a range of users.

The book utilizes cartoons to illustrate and explain statistical concepts and procedures, making learning more engaging and less intimidating.

The book uses cartoons to visually represent statistical procedures, making them easier to understand and remember.

This edition includes new content such as chapters covering charts for repeated-measures data and an introduction to hypothesis testing.

Each chapter covering hypothesis tests now includes a section dedicated to helping students interpret results and determine if they are significant.

This edition of the book includes a section on scree plots in factor analysis, which is a useful tool for identifying factors.

The book uses a user-friendly approach to statistics designed for students who might be intimidated by the subject. Cartoon illustrations and clear explanations make it more approachable.

The book aims to empower students by helping them develop a sense of confidence and understanding in their ability to analyze data.

A user-friendly software package designed for statistical analysis, commonly used in social, behavioral, and educational sciences.

Specific inquiries or problems that a study aims to answer or address using statistical analysis.

Deciding which statistical procedure is the most suitable for a given research question and data type.

A method of presenting information in a clear and structured manner, guiding users through each stage of a process, like SPSS analysis.

Understanding and interpreting the results produced by SPSS, drawing meaningful conclusions from the statistical data.

Manually calculating statistical values using formulas, often used to verify results obtained from software like SPSS.

Exercises designed to reinforce learning by applying statistical procedures and concepts in real-world scenarios.

The technical process of conducting statistical analysis using SPSS, including entering data, selecting procedures, and running analyses.

The results of a paired-samples t-test displayed in SPSS, showing three main parts: Paired Samples Statistics, Paired Samples Correlations, and Paired Samples Test.

This part of the output presents basic descriptive statistics (mean, sample size, standard deviation, standard error) for each of the two related variables.

This section indicates the strength of the relationship between the two variables; a value closer to 1.00 suggests a stronger relationship.

A variable that categorizes individuals into groups, like 'gender' or 'treatment condition'.

A variable that measures a characteristic, like 'height' or 'test score'.

This part shows the mean difference between the two groups and the standard error of that difference, which are used to calculate the t-value.

The difference between the average score of the first group and the average score of the second group.

A way to describe how often each category appears in a group variable (what percentage of the group belongs to each category).

A measure of how much the mean difference between the two groups might vary.

A summary of the 'typical' value in a score variable (like the average, most common, or middle value).

A measure of how spread out the scores are in a score variable (how much difference is there between the scores).

A statistic calculated from the mean difference and standard error of the difference, used to assess the significance of the difference between two groups.

A correlation value closer to 1.00 indicates that the observed change is more consistently experienced by participants, potentially leading to a stronger t-value and a greater likelihood of finding a significant difference.

Checking if the score variable's distribution resembles a bell-shaped curve (normal distribution).

A statistical test comparing the means of two groups, assuming the groups are independent (scores are unrelated).

A statistical test comparing the means of three or more groups, assuming the groups are independent (scores are unrelated).

A measure of the relationship between two score variables (how strongly they change together).

A statistical technique predicting a score variable based on the values of one or more predictor variables.

The independent variable is the factor that is being manipulated or changed by the researcher. It's the variable that is expected to have an effect on the dependent variable. In this study, the type of chili sauce (Poblano, Jalapeño, Habanero) is the independent variable since it's the factor that is deliberately varied.

The dependent variable is the outcome that is being measured, or what is being observed to see if it changes in response to the independent variable. It's the variable that is expected to be influenced by the independent variable. In this study, the dependent variable is the eruption time (in seconds) because it's the duration of the reaction after tasting the chili sauce.

The population is the entire group of individuals that the research findings are meant to apply to. In this study, the population is all eight-year-olds. This is because the study aims to understand the reaction of eight-year-olds to different chili sauces.

The sample is a smaller group of individuals selected from the larger population. This group is studied and observed to draw conclusions about the population as a whole. In this study, the sample is the 30 eight-year-olds who participated in the experiment.

The study uses quantitative data, which is numerical information used for measurement. In this case, the data involves measured time intervals in seconds for the children's eruption reactions.

This study is an example of experimental research, which involves manipulating one or more independent variables to observe their effects on the dependent variable, while controlling for other interfering factors.

A one-way ANOVA (Analysis of Variance) is a statistical test used to compare means across multiple groups when the independent variable has only one factor. It helps determine if there is a significant difference in the average eruption time across the three chili sauce groups.

In SPSS, a value label is a descriptive text assigned to a numerical code. This provides a more readable label for each group in the data, making it easier to understand the meaning of the numerical codes. In this case, the value labels “Poblano,” “Jalapeño,” and “Habanero” are assigned to the numerical codes 1, 2, and 3 respectively.

A table in SPSS output that summarizes key statistics for each group in your data, such as sample size (N), mean, standard deviation, and minimum & maximum scores.

An estimate of how much the sample mean is likely to vary from the true population mean. It's calculated by dividing the standard deviation by the square root of the sample size.

A range of values within which we are confident (usually 95%) that the true population mean lies. It's calculated based on the sample mean and standard error.

A table that presents the results of an ANOVA test, breaking down the total variability in the data into different sources of variation (between groups and within groups).

The variability between the means of different groups. This represents the effect of the independent variable on the dependent variable.
