Ultimate Guide to Statistics for Grouped Data

Don't worry... This book is designed to explain everything you need to know about statistics for grouped data in a clear, step-by-step, and straightforward manner.

You won't find boring definitions or meaningless formulas here. You'll see a well-explained example from beginning to end.

You'll learn how to create a frequency distribution table from scratch, how to calculate the mean, median, and mode intuitively, and how to understand what quartiles, deciles, and percentiles are and how to calculate them.

Plus, at the end, I suggest some exercises for you to practice on your own and test what you've learned.
