What Is Statistics?

Statistics refers to the type of applied mathematics that explores the collection and analysis of conclusion from data. The math theories that back statistics rely quite a bit on calculus, algebra, and probability theory. Statisticians, who are professionals who engage in statistics, are usually concerned with figuring out how to draw reliable and accurate conclusions about groups and events from the characteristics of samples. These samples are used to represent a portion of the greater group or a smaller number of instances of a greater phenomenon. Descriptive statistics and inferential statistics are the most commonly used types of statistics that are used to describe data and draw conclusions.

To put it simply, statistics is basically the study and process of changing data. Statistics can be used to make well-informed decisions in the world of science, math, business, investing, and so on.

Statistics is used constantly throughout our day-to-day activities, both in our everyday lives and in a variety of different industries. It is used in industries such as data science, robotics, meteorology, business, engineering, and more. Statistics can be used to calculate the success of medical treatment implementation as well as the probability of rain on a particular day.

How to Approach Learning Statistics

Don’t let statistics intimidate you! There are only a few things you need to do to prepare for taking a statistics course.

To start, refresh your brain on basic math concepts, such as PEMDAS and basic arithmetic. From there, revisit your algebraic knowledge. Most students must pass an algebra course before moving on to statistics. When you begin your statistics course (or when you’re studying shortly before starting), make sure you can grasp the basic fundamental principles. 

Always ask for help when you need it. Statistics is complex, and your professors know that. If you miss just one concept, you could be left confused for the rest of your course. Get help today with an online statistics tutor.

Statistics Student Curriculum FAQs

High school statistics courses seek to help students understand the core fundamentals and use cases of statistics. Specifically, most high school and introductory statistics courses will explore the basics of collecting and analysing data. Such classes will also explore the use inferences and conclusions, as well as probability. 

In such classes, students can explore how statistics can be used to determine the cause of an event in a case study as well as the probability of an event occuring. Some common topics in statistics that are also taught include linear models, inferences, conclusions, the rules of probability, statistical experiments, conditional probability, and categorical and quantitative data. By the end of their high school statistics course, students should be able to make basic decisions using statistical probability.

Statistics courses offered to first and second-year college student will take what they’ve learned in high school a few steps forward. In order to take statistics classes in college, one will need to meet prerequisitcs from high school or have a satisfactory SAT or ACT score. There are many concepts taught in college statistics. A few include the following:

  • Understanding distributions via graphs.
  • Describing distributions with numbers.
  • Complex normal distributions.
  • Complex sampling and the basics of how bias affects results.
  • Complex probability.
  • Binomial and sampling distributions.
  • Confidence intervals and tests of significance for single means.
  • The basics of scatterplots and correlation.
  • The basics of regression.
  • Understanding and building two-way tables.

For students that choose to study more advanced statistics in their final two years of university, there are many new and very complex areas to explore. A few well-known topics taught in advanced statistics classes include:

  • Advanced statistics, both in concept and application.
  • Quantitative methods.
  • The role of statistics in relevant student fields or majors, such as science, economics, business, medical, etc.
  • The use of hypothesis testing for various sizes of samples.
  • The concepts of chi-squared. Statistical quality control, complex correlation, and complex regression.
  • The basics of analysis of variance.

It’s also worth noting that many other courses, such as advanced mathematics and science classes, will involved advanced statistics as well.

How Do I Become a Statistics Tutor?

If you have a passion for teaching others and love statistics, becoming a statistics tutor is easy. You need a minimum of a high school degree or GED to start teaching kindergarten and middle school grade levels. You may need a degree in a specialist subject for higher-level statistics courses depending on the level of practice you plan to teach. The costs of statistics tutors vary because you will set your pay rates and time schedules depending on your own experience and circumstances.

Your first step will be to decide which topics you’d like to tutor. Then choose the age groups and grade levels you want to teach. Learn the curriculum and critical concepts for those grade levels. And lastly, establish your teaching methods, tools, and eventually, you will create your own course materials over time as you get more experience working with students.
