Introduction
As a new intern at an educational charity, I will be exploring the use of big
data and data analytics to improve programs. The charity is looking to
understand how GCSE results in England vary across different Local
Authorities and genders. I will use statistical techniques to analyze and
evaluate the data, including tabulating and visualizing the data, calculating
the central tendency, applying probability distributions, conducting
regression analysis. The findings will be in the report below, which is
accessible to stakeholders with a mathematical background, enhancing the
charity's impact on educational outcomes.

Pie Chart
A circular graph that has been broken into parts to reflect various data
proportions is displayed in a pie chart, a data visualisation tool. The size of
each slice will correspond to the quantity it represents, and each slice
represents a category of data. Pie charts are a popular visual data
presentation tool in business, journalism, and other areas. They help to
facilitate quick understanding of the relative proportions of distinct
categories. They are helpful in giving numerical proportions an easy-to-
understand format and in showing data analysis.
Below I will provide you with the two pie charts I made using the data set for both boys and
girls to show their performance. This is a very good method to show how much space a single
region can occupy. Pie charts can divide full data set into sections to further simplify one’s
understanding. The chart is shaped like a large round circle pie, as implied by the name pie, and
it fully shows the set of data, which is broken up into several pieces or slices. This helps to
further illustrate show each proportion and percentage for each category because of each slice
of the pie is a subcategory of the overall GCSE data set.
