**Fix Your Maths Fast: Volume 3**
A clear, practical, stress-free guide to statistics, probability, data and research maths — explained in plain English.
If terms like standard deviation, correlation, p-values, confidence intervals or sample size leave you feeling lost, this book was written for you. It breaks statistics and research maths into simple, friendly shortcuts, with extra explanation of standard deviation, confidence intervals and skew.
This is not a heavy textbook. It is a confidence-building companion for learners who want clear explanations, useful examples and simple ways to understand numbers.
Inside, you will learn:
– Statistics made easy — data, variables, averages, spread and interpretation
– Probability explained simply — chance, likelihood and probability trees
– Standard deviation, variance, standard error and confidence intervals
– Correlation and causation — and misleading patterns to watch for
– Spearman’s rank correlation in plain language
– Research methods — surveys, experiments, observations and interviews
– Populations, samples, bias and sampling
– Statistical significance and p-values
– Graphs and data displays, including misleading scales
– Skew, outliers, mean, median and mode
– Real-world statistics in headlines, risk and claims
Each shortcut explains what the idea means, why it matters, how to use it, what to avoid, and how it applies in real life.
Ideal for students, adult learners, parents, tutors and home educators.
Fix your maths, understand the evidence, and question numbers with confidence.
