Free Statistics Calculator & Data Analyzer

Statistics requires managing massive datasets and tedious probability formulas. Welcome to Zimbook’s Free Statistics Solver. Whether you are finding the standard deviation of a sample, calculating permutations and combinations, or mapping out a probability distribution table, our engine does the heavy lifting for you. Build your datasets using our specialized mathematical keyboard below to generate instant, step-by-step statistical breakdowns.

How to Use the Statistics Solver

We designed our custom layout to handle the unique formatting requirements of high school and college statistics courses:

Probability & Combinatorics: Use the nPr button to calculate permutations (when order matters) and the nCr button for combinations (when order does not matter).

Datasets & Arrays: Need to find the mean, median, or mode of a list of numbers? Click the [■,■] button to insert a dataset array, and separate your values with commas.Data Tables: You no longer need to format tables manually. Click the x|y button to instantly generate a 2-column data table, or use the x|P(x) button to build a probability distribution table.Specialized Symbols: We have included quick-keys for all vital statistical symbols, including the population mean (μ), sample mean (x̄), and standard deviation (σ).

Master Data Analysis

Zimbook doesn't just output a final number; it shows you the mathematical journey. When you input a dataset, our engine translates it into the strict formulas required for variance, standard error, and normal distribution. This makes it the perfect tool for checking your homework, studying for AP Statistics exams, and mastering data science fundamentals.

(Note: If you are looking to calculate basic percentages, fractions, or algebraic expressions, please head over to our Basic Math Calculator instead!)

Frequently Asked Questions

How do I enter a list of data or a dataset?

To enter a dataset, click the [■,■] button on the custom keyboard to create an array bracket. Then, simply type your numbers separated by commas (for example: [12, 15, 18, 22, 25]). Once you hit 'Analyze Statistics', the engine will automatically calculate the mean, median, mode, standard deviation, and variance for that set.

What is the difference between nPr and nCr?

These buttons are used for combinatorics and probability. Use nPr (Permutations) when the order of your selection matters (like a combination lock or a race finish). Use nCr (Combinations) when the order does not matter (like selecting a committee of 3 people from a group of 10).

Does the calculator provide Sample or Population Standard Deviation?

It provides both! Because it is impossible for the calculator to know if your dataset represents a full population or just a sample, our engine calculates and displays both the Sample Standard Deviation ( $s$ ) and the Population Standard Deviation ( $\sigma$ ) so you always have the exact number you need for your homework.

Can I build two-variable data tables?

Yes. You don't have to spend time formatting spaces or tabs. Just click the x|y button to generate a standard two-column data table, or click the x|P(x) button to instantly drop in a formatted probability distribution table template.
