Statistics Defined
This chapter in Surviving Statistics lays the foundation for all upcoming chapters. It covers quantitative and qualitative variables, measurement scales and other important foundational concepts.
Descriptive Statistics – Frequencies
This chapter in Surviving Statistics introduces one aspect of descriptive statistics, frequency distributions. One of the first things you will want to do with your data is count the number of occurrences by category. This is what frequency distributions help you do.
Descriptive statistics – Numerical Methods
This chapter in Surviving Statistics explains measures of central tendency and dispersion. It will cover mean, mode, median, variance, standard deviation and more.
Exploring Data
This chapter in Surviving Statistics explains measures of Position including median, percentiles, and deciles.
Exploring Probability Concepts
This chapter in Surviving Statistics explores computing probabilities, which is essential when working with statistics.
Discrete Probability Distributions
This chapter in Surviving Statistics explores Discrete probability distributions including Binomial and Poisson distributions.
Continuous Probability Distributions
This chapter in Surviving Statistics explains measures of continuous probability distributions including uniform and normal distributions. This chapter also introduces working with Z scores.
Sampling and Sampling Distributions
This chapter in Surviving Statistics explains different sampling methods and how sample data can be representative of population data.
Confidence Intervals and Point Estimates
This chapter in Surviving Statistics explains how to compute and use confidence intervals.
Hypothesis Testing: One Sample
This chapter in Surviving Statistics explains how to complete a Hypothesis testing with one sample.
Two sample hypothesis testing
This chapter in Surviving Statistics explains how to complete a Hypothesis testing with two samples.
ANOVA (Analysis of Variance)
This chapter in Surviving Statistics explains how to complete an Analysis of Variance when working with two populations or more than two samples.
Correlation and Linear Regression
This chapter explains computing the Correlation Coefficient, dependent and independent variables and performing linear regression manually and with Excel.
Goodness of Fit Tests
This chapter explains computing the goodness of fit for equal and unequal frequency distributions.
