When is calculus used in statistics




















Interestingly for me, statistics and physics were something of college nemeses for me. However, statistics also opened up a whole new way of approaching the world. Statistics by nature is meant to explain groups of data. For example, I might look out at a marina and see a group of yachts. For example, rocket scientists might use calculus to figure out how to design and build their rocket, but then use statistics to figure out where to land it.

When it comes to market research, we tend to spend plenty of time focused on the statistical analysis needed to answer various questions such as: what pricing strategy will allow me the maximum profitability and not drive away my desired customer base; what price is right ; what product enhancements will my customers actually want to see in the next product release?

However, I credit my calculus education for a lot of the original problem-solving strategies I still employ when looking at data sets. Though you're welcome to continue on your mobile screen, we'd suggest a desktop or notebook experience for optimal results. Survey software Leading survey software to help you turn data into decisions. Research Edition Intelligent market research surveys that uncover actionable insights. While I'm sure there are many on this site who will disagree, I'd like to play devil's advocate for a moment and argue that no, calculus is not really necessary to be a good applied statistician or data science person.

It is true that advanced mathematical techniques, including calculus, are necessary to derive the mathematical theory behind statistical methods. However, I would like to argue that in general it's not necessary to understand the math behind the statistical method in order to apply the method.

For example, one of the most common methods applied is the t-test. In order to use the t-test, people need to know a serious of rules regarding when it is and is not appropriate. They do not, however, need to be able to derive the result that the t-statistic follows a t-distribution. Yes, calculus is required. Statisticians must work with moments.

To understand moments, you have to know calculus. It's the same with calculating tail probabilities or using maximum likelihood - you can't effectively do either in a non-textbook application without an understanding of calculus. You may not use it on a daily basis, but you will use it periodically. Sign up to join this community. The best answers are voted up and rise to the top. When we speak of the probability of throwing a "natural" in dice, or the probability of living to age 65, we are asCribing probabilities to properties.

When we speak of the probability that John Q. The mathematical theory is often called the probability calculus. Data sets are often continuous. Many statistics operations rely upon probabilistic approaches.

Calculus and Statistics are Complementary: so try to learn both. For example, rocket scientists might use calculus to figure out how to design and build their rocket, but then use statistics to figure out where to land it. The three biggest uses of calculus in probability are 1 doing infinite sums to understand discrete problems, like sequences of coin flips, 2 doing integrals to understand continuous random variables, and 3 doing double and triple integrals when you have several related variables.

Which is harder calculus or statistics? To sum up in a sentence: Calculus involves real, solid math whereas statistics asks one to evaluate the situation and do algebra with it.

I took stats this semester and all I can say is, I learned a new language! For me, stats was a lot more difficult than calculus; almost night and day.

Do statisticians use calculus? Yes, calculus is required. Statisticians must work with moments. Put aside for a moment the methods for differentiation and integration and think about the tools and language one needs to describe relationships among variables. Calculus and statistics both center on models of relationships: constructing them, analyzing them, evaluating them. In calculus, the choice to add a term to a model reflects some knowledge or hypothesis about mechanism. In statistics, choices are based on evidence provided by data.

These are complementary perspectives with a shared foundation in mathematical modeling. This general-purpose form—extended often to more than two variables but remaining linear—is the workhorse of statistical modeling. An important strategy from calculus is the partial derivative—examining the change in outcome as one input is changed while others are held constant.

This aligns with experimental method in science; examining partial change and developing a formal language for describing it helps students understand that there are different ways for change to happen. Ideally, statistical notions of fitting functions to data are taught hand in hand with the introduction of functions and their parameters in calculus. With this, and with the idea of partial change, students are better able to make mathematical sense of statistical ideas such as adjustment and how the relationship between two quantities, z and x , is informed by the participation of additional quantities.

Although it serves needs of all the disciplines, the primary orientation is toward statistics even using R software for teaching calculus. In one semester of calculus, students gain experience building and interpreting models in multiple variables.

Then, when they move on to statistics, they can connect their models to data and examine and evaluate the extent to which the data provide evidence for their models.

The success in making elementary statistics accessible without calculus is remarkable.
