Statistics Challenge – Be Sure You Know the Basics

A basic knowledge of statistics helps you understand and appreciate the uncertainties surrounding statements about data or information.

If you are unsure about whether you (still) know the basics, then testing yourself is a quick way to find out. Here, you have many opportunities to do exactly that.

The opportunities cover the following topics:

Probability, descriptive statistics (mean, variance, median, inter-quartile range), interpreting data, calculating (relative) frequencies, quartiles, correlation, outliers, boxplots, histograms, design of experiments (randomized, blocked), placebo study, hypothesis testing, z-scores, confidence intervals, P-value, significance level, normal distribution, t-distribution, Chi-squared distribution, binomial distribution, geometric distribution, simple regression, statistical inference, sampling from a population (random, stratified, cluster), observational study, testing for proportions and means in a population, testing for differences in proportions or means between populations.

Three sets of 40 opportunities.

Each opportunity is a question appears with 5 possible answers. There is only one right answer. You have to chose the right one.

The opportunities ask you to interpret data (in tables or figures), to understand the context of the question, to evaluate statements about a statistical issue (sometimes more than one is correct), to calculate relative frequencies and probabilities.

A broad scope of statistics material

The questions cover the following subject-matter:

• Descriptive statistics of data with one and two variables.

• Sampling from a population.

• Designing experiments.

• Sample means and proportions.

• Probability and random variables.

• Probability distributions.

• Inference.

You are probably fine to confront the informational challenges in real life if 70% percent or more of the test opportunities are no challenge for you anymore.

Features of the challenge:

• To save time, try to challenge yourself with 40 test opportunities in 90 minutes.

• If needed, you can pause the challenge and resume it later. Your progress will be saved.

• You will get a breakdown of questions you answered correctly and incorrectly.

• An explanation for each question.

• You can mark questions for review later after completing the test.

• You can search back for questions related to one of the knowledge areas.

• You can review all answers.

• You can take the challenge as often as you want.

After taking the challenge, you can find out how well you did in these areas: statistical reasoning, identifying statistical methods, analyzing data and understanding probability.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
