Spreadsheet Analysis
By Catherine George
Introduction

In this PowerPoint I will be analysing the good and bad points about 2
different spreadsheets.

I will be specifically looking at the purpose, what the data shows, what data
they have, features of the spreadsheet (formulae), features that would
improve productivity, accuracy and usability. I will also give strengths and
weaknesses of each spreadsheets and the improvements that could be made
to improve these weaknesses.
Purpose of spreadsheet

Belgrave School

T-Shirts

The purpose of this spreadsheet is
to show the examination analysis
of the students exam results from
2012-2013 in Belgrave School.

The purpose of this spreadsheet is
to show the profit and loss account
of L&C T-shirts up to 2013.

The spreadsheet shows the sales
turnover, cost of the sales, gross
profit, expenses and the net profit.

The spreadsheet shows the
students name, teacher, the paper
marks and percentages, the total
marks, whether they passed or
failed and how far above or below
the national average the students
are.
Data they have…

Belgrave School

T-Shirts

The data included in this table is the
date, the pupils first name and surname,
the students teacher, the marks and
percentages for paper 1, 2 and 3, the
total marks, if they passed or failed,
whether they are above or below the
national average, what the national
average is and the number of students
who passed and failed.

The data included in this spreadsheet is
the sales turnover, cost of sales, gross
profit, expenses and the net profit.

The sales turnover allows the reader of
the spreadsheet to see how much money
is made without anything taken off of the
total. The cost of sales column allows the
reader to see how much it costs to set the
business up. The gross profit allows the
reader to see how much money is made
after the initial costs are taken off. The
expenses allow the reader to see how
much money is made by the company
once all of the expenses has been taken
off. The net profit allows the reader to
see how much money is made in total.

The pupils first name, surname and
teacher allows the person reading the
spreadsheet to identify the students. The
marks and percentages allow the teachers
to track whether the students are
understanding the work and what marks
they got. The grade allows teachers to
easily see who has passed or failed.
What does the data show…

Belgrave School

T-Shirts

The data in this spreadsheets shows
whether the students have passed or
failed overall in their exam. It also
shows how far away from or above
the national average they are. Finally
it shows the mark the students
achieved for each paper and the
percentage which allows the teacher
to see which area the students are
struggling with. The spreadsheet
shows that the majority of students
passed however a high percentage of
students failed.

This data shows the profit and losses
made by the t-shirt company. Overall
it shows that the company made a
profit once all of the expenses were
taken off. It also shows that they
didn’t make as much profit as they
could have done if they reduced the
expenses.
Features of Belgrave School
This is a function that
makes the date appear in
the corner of the screen.
This is a formula
that calculates
division, it is used
to work out a
percentage in this
spreadsheet.
This is a formula to
calculate addition,
it is used to add up
test scores in this
spreadsheet.
This is a
validation drop
down menu
that allows the
person making
the spreadsheet
to pick the
name of their
teacher easily
and quickly.
These columns have been
grouped by colours so
that it is obvious to the
reader of the
spreadsheet that they
are related. This layout is
used to help the reader
to see the information
they need quickly. This is
also an example of
formatting
Features of T-Shirts
This is a formula
used to calculate the
cost of the products
needed to run the
business.
This is a function
used to count up
all of the
expenses needed

of formatting as
all of the totals
have a double line
underneath to
make it easier to

totals are.
The layout of this
spreadsheet is
very simple and
isn’t very
effective. The
most effective
layout is the 2 last
columns. The first
column shows the
amount of money
spent on each
aspect of the
business. The
second column
shows the totals
such as nett
profit, total
expenses, sales
turnover etc.
Belgrave School- Productivity, Accuracy,
Usability

In this spreadsheet there are many features that could improve productivity. All
calculations needed to be performed are done so using a formula which can be
filled down to perform the same calculation for different data. It is very easy to
manipulate the data because the spreadsheet is colour coded and organised in
alphabetical order. An example of data manipulation in this spreadsheet is the
comparison to the national average. Conditional formatting is used in the pass or
fail column, making it easy to determine whether a student has passed or failed.
Function is used to present the date and formulae is used to do every calculation
on the spreadsheet.

The features of this spreadsheet also improve accuracy. Data validation is used in
the form of a drop down menu. There isn’t any cell protection in this spreadsheet.
This spreadsheet uses an IF statement to make accurate decisions as there are
only 2 answers available.

This spreadsheet has colour coding to help navigate through the spreadsheet
quickly. The marks and percentage for each test are grouped together to help
associate them as a group in the readers mind. This would help the reader to
navigate the spreadsheet quickly and easily.
