Spread Sheet Evidence
Creating the Database
I made a spread sheet to collect all the information from the questionnaire that I
created. It is an easy way to view a lot of information at once. I made all the
titles of the question and then made drop down boxes so that it was easier to
get in all the information.
Creating Drop Down Boxes
I have chosen to use
drop down boxes for
the answers to the
questionnaire as it is
easier to pick from
the choices rather
then typing it all in.
I used the data
validation rules to
create the drop
down box.
I wrote down the options in a blank
cell and then highlighted them as my
formula so I can choose from them in
my drop down box.
Countif Statements
First I chose to change the name of my information, e.g.
here I changed it to “gender” instead of leaving it as the
cell number. I did this as it will be easier when doing my
countifs to type in the name of the column instead of
changing sheets to find the information. To do this I
highlighted that section on my data sheet and then typed
in what I wanted to call it at the box on the left hand side
of my sheet.
Here we can see how I did
not have to type in the
values as we have already
changed it all to “male”
this makes it easier to do
our formulas.
This would be where it
comes from so B4:B23
Countif statements are an
easy way to count how
many of an option there
is. First I wanted to find
out how many boys and
girls were in the survey
The criteria would be “male”
or “female”
To do this we do the equation
=COUNTIF(in the brackets you do the cells
where the information is, “the option you
are looking at”) In this case its
(B4:B23,”Male”) after this we can change
it to “female” Instead of typing in the cell
number we can say “gender” instead as we
changed the title at the start.
Countifs Statements
Countifs
After completing the Countif
statements I wanted to analyse my
data even more so I did countifs
statements. These are used to
retrieve two bits of data and to
count them. For my work I wanted
to find out how many boys and
girls were in each option.
To do the countifs statements I
went into function arguments
and stated the criteria range,
here I went back to my first
sheet and retrieved all the data I
needed. I wrote “male” and “13”
to see how many 13 year olds
were male.
Graphs
I made graphs to show the results more clearly. I did two
graphs to show the Countif statements and the countifs
statements. This will show me which is the most popular
option and which is most popular among boys and girls.
I can then analyse them to get more information from them
to use in other parts of the project. Graphs are very helpful as
it is a good easy way to layout large amounts of data.
To create the graphs I
had to highlight the
information and go on
data, and choose which
graphs I wanted to do. I
chose bar graphs for
nearly all of them as I
think they are the
easiest to view and show
your information in an
easy clear way.
I have added labels to my graphs so
you can see the exact numbers
from which the bars are and from
a distance you can easily see them.

Testing of the spread sheet
When I typed
in the value
“bread” it
came up as an
error to show
my value was
not valid. This
shows my
validation rules
worked as it
did not allow
me to type in
any values
which were not
in the rule.
