Frequently Asked Questions

CheggMate offers an online calculator specifically for statistics that can perform a wide range of calculations, including standard deviation, variance, range and normal distribution. It also provides detailed step-by-step solutions.

Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. There are two main branches of statistics: descriptive statistics, and inferential statistics.

Descriptive statistics is a branch of statistics that deals with summarizing, organizing and describing data. Descriptive statistics uses measures such as central tendency (mean, median, and mode) and measures of variability (range, standard deviation, variance) to give an overview of the data.

Inferential statistics is a branch of statistics that deals with making predictions and inferences about a population based on a sample of data. Inferential statistics uses probability theory and statistical models to make predictions and inferences about a population.

Statistics is the branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data, while probability is the branch of mathematics dealing with the likelihood of occurrence of different events.

Statistics Calculator: Turning Analytics into Game-alytics!

If I could earn a dollar every time someone lamented the difficulty of math homework, I'd rival the wealth of Bill Gates. But is math truly as challenging as it seems, or is it our perception that makes it so?

Mathematics, like any discipline, demands consistent practice to master its formulas, equations, and theorems. You can't expect to glance at math rules and instantly become Einstein. The world doesn't operate on such whims.

Even in fields like art and literature, practice is paramount. So, if you're serious about mastering math, you need training, and it's time to start.

The challenge lies in the difficulty of practicing math without guidance to spot your errors and weaknesses. Fortunately, our statistics p-value calculator is here to lend a hand.

What is Statistics?

Statistics is the discipline of extracting insights from data. It's essential for scientists to make discoveries and for economists and experts to predict and decide based on input values. After data collection, statistical analysis generates various values and equations to provide valuable information about a subject, deepening our understanding of its behavior.

Why Learn Statistics?

Studying this subject is crucial in today's society, where decision-making heavily relies on statistical analysis of uncertain situations. Being able to critically evaluate others' work is vital.

Moreover, experts in this field excel at using collected data to solve misleading problems common in fluctuating industry environments.

In this section, we'll delve deeper into these two primary reasons for studying this fascinating field, which lies at the heart of creating new knowledge from existing information. Stay tuned.

Statistics Uses Numerical Evidence to Draw Valid Conclusions

Statistics may seem like a field of numbers, like the claim that 9 out of 10 doctors recommend a brand. In reality, it's a set of methods and equations for data analysis. It quantifies aspects of variables, and these measures accumulate to evaluate situations and actions. This is crucial today, as data is abundant and motives behind certain interpretations can be dubious.

Statisticians provide a roadmap to navigate environmental uncertainty, ensuring they avoid pitfalls that lead to erroneous decisions. When they follow the field's methods, their results are precise, with a known margin of error.

This is backed by experience. Statisticians ensure that the steps to worthy results—producing useful information, studying it thoroughly, and making sound deductions—are seamless.

Statisticians Know How to Avoid Common Pitfalls

The statistical process is complex, with many steps, including choosing methods, selecting inputs, measuring, testing, and filtering information. Output accuracy depends on these decisions, and a simple mistake can lead to erroneous results. Some issues include:

Biased Samples

If the study's basis doesn't reflect generalized facts, conclusions will be skewed from the start.


Properties deduced from specific groups may not apply to others. Limitations are often unclear, but awareness is crucial.


This relationship is challenging to pinpoint, often confused with correlation. Statistical studies require specific criteria before assuming causation. Just because A precedes B and they correlate doesn't mean A causes B!

Incorrect Analysis

Some statistical tools are more suitable for certain situations. Using the right ones for your case is vital.

Violating Assumptions for an Analysis

Every study has properties that form its basis. Breaching these increases the risk of erroneous results, especially when they're only applicable under certain conditions.

Data Mining

When analyzing a dataset, note the number of tests performed to maintain context. Prolonged study can produce false patterns.

Producing accurate results requires the accuracy of the foundations. Experts ensure correctness in this field.

Use Statistics to Make an Impact in Your Field

Every field processes considerable data, and statistical studies analyze and quantify this information. Even if your studies aren't based on statistics, they can enhance your career.

At least, you'll need basic knowledge to apply statistical concepts for conclusions, decisions, and understanding others' studies. That's why daily practice with our statistics probability calculator is essential.

If you're a statistics graduate, your skills are in demand across industries. Your flexible knowledge complements other expertise and aids understanding.

Lies, Damned Lies, and Statistics: Use Statistical Knowledge to Protect Yourself

Mark Twain's phrase linking lies to statistics can be true. Analysts can skew data or processes for specific outcomes.

Remember the analysis mistakes? They can be used intentionally to manipulate results. Without familiarity, detecting these is challenging. Your knowledge is key to avoiding such situations and ensuring result integrity.

Practice daily by solving different statistical problems and verifying results with our online statistics calculator.

How to Learn Statistics

Set a Plan Instead of tackling any problem, establish a practice plan for long-term consistency. For example, allocate one or two hours, five or six days a week. Cramming sessions are counterproductive.

TL;DR: Plan your studies and distribute practice throughout the week.

Form a Study Group

Group study sessions can enhance your performance and understanding through interactive verbal exchanges.

Don't Memorize Formulas

Focus on concepts and practice them according to your study plan. In the future, you can use a calculator or the internet for formulas, but they won't help with understanding concepts.

Practice Different Types of Problems

Vary your practice by working on different, varied problems to cover multiple statistical concepts.

Hunt Reoccurring Themes

Identify recurring themes and focus on them to acquire essential statistical skills.

Understand the Problems as a Whole

Comprehend each part of a problem before solving to grasp the overall situation, making the process easier.

Solve Your Math Anxiety

If you suffer from math or statistics anxiety, seek help from your school or university, as they often provide counseling programs and services.
