Exhaustive Events – Definition & Examples

Consider an experiment whose outcome is not predictable with certainty in advance. Although the outcome of the experiment will not be known in advance, let us suppose that the set of all possible outcomes...

Relative Frequency Polygon – Definition & Examples

A relative frequency polygon is a frequency polygon where we plot the relative frequencies instead of the actual frequencies on the Y-axis. The data values are plotted along the X-axis as in the usual...

5 Examples of Positive Correlation

Roughly speaking, we say that two variables are positively correlated if an increase in value of the first variable causes an increase in the value of the second variable and a decrease in the...

Flip a Coin 100 times – Probability Calculations

When we flip a coin once there are 21=2 possible outcomes - H (heads) or T (tails). When a coin is tossed two times there are 22=4 possible outcomes - HH, HT, TH, TT....

Set Builder Notation – Explained with Examples

The set builder notation is one of the methods that is used to represent sets. The other method used to describe the elements of a set is the roster form. Suppose we are given...

-2^x Graph – Step by Step Explanation

In this article, we will understand how to draw the graph of the function -2^x. We will then see how to construct the graph of (-2)^x. The graph of the function 2^x asymptotically tends towards...

Tally Marks – What is it? Explained with Examples

Tally Marks are used to represent the frequency with which a particular value occurs in a given set of data. A single occurrence of a data value is represented by one vertical stroke. So...

Horizontal Bar Graph – Explained with Examples

Bar graphs are the most common type of diagrams used for visualizing data. They are readily understood by those who are not used to reading charts. They are also simple and easy to make....
