7 Common Graphs in Statistics

Graphs help statisticians to visualize data. But not all graphs are created equally. Different situations call for different depictions of data. Learn more about seven of the most common graphs in statistics, and when you should use them.

What Is a Paired Difference?

Paired differences arise in statistics when working with paired data. See how to form a paired difference and why we use these.

Pascal, Fermat and the Birth of Probability

Learn more about the beginnings of probability when Pascal and Fermat teamed up to solve a problem involving dice.

Common Maclaurin Series

See formulas for some of the most common Maclaurin Series

What Are Maclaurin Series?

Maclaurin Series use the derivatives of a function as coefficients in a power series. They can be used for a number of applications.

Use of the Moment Generating Function for the Binomial Distribution

See how to use the moment generating function to calculate the mean and variance of a binomial distribution.

What Is the Moment Generating Function of a Random Variable?

The moment generating function of a random variable is related to a particular expected value.

Luca Pacioli and the Beginnings of Probability

One of the origins of probability stems from when Luca Pacioli posed a mathematical question regarding a game of chance.

What Is the Geometric Series Test?

There is an easy test to determine if a geometric series converges. We also see a formula for determining the value of a convergent geometric series.

What Are Absolutely and Conditionally Convergent Series?

There are two types of convergence. Find out the difference between absolutely and conditionally convergent series.

Proof that the Harmonic Series Diverges

The harmonic series is counterintuitive in that it diverges although its terms seem to decrease quickly enough for the series to diverge. See a proof of why this series diverges.
