# Do you know about Normal Distribution?

Plotting the results of statistical analysis on a graph and studying the shape of the curve has a huge variety of uses beyond mathematics.

The normal distribution, also known as the 'bell curve', is a mathematical function that describes the distribution of data. The normal distribution can be seen everywhere; shoe sizes, birth weights and stock market returns, all follow a normal distribution pattern. Normal distribution can be used to calculate probabilities of events. In GCSE and A-Level mathematics, students will use it to predict probabilities of dice rolls and coin tosses. The applications for this distribution are almost endless due to its constant presence in nature and society.

Businesses look at the pattern of responses to market research questions. For example, although the arithmetic average may be 6 out of 10 for an answer on the likelihood of a consumer buying a product, the business will check the distribution of the responses. If normal distribution is absent, with results skewed to the right, the statistics may indicate the presence of a niche market.
