Writing Time!!!!
P1: Explain how spreadsheets can be used to solve complex problems.
Think about the attendance register that you have made so far and the techniques and features you
used.
First to answer this question all you need to mention is how we can use additional worksheets, complex
formulas (NESTED IF, for allocation of grades and formula to calculate the attendance percentage),
cell linkage, data validation, drop down list and cell protection, such advanced features to help you
solve complex problems.
Secondly explain goal seeking and how and why it can be used. Use the notes on goal seeking to help
you answer this part. This is mainly to show a tool within spreadsheet to help solve complex
problems.
Third, how we can use mathematical functions such as average , count, sum to help analyse data. Again
use the attendance register and explain why you have used these functions to help you analyse the
data. (YOU CAN USE THIS INFORMATION ALSO TO HELP YOU ANSWER D1)
D1
Discuss how organisations can use
interpretation methods to analyse data.
Again we have a lot of data within our
spreadsheet. How can we interpret it or take
information from the data that we have.
Likewise other organisation such as
companies, colleges, charities etc will also
need tools to interpret and analyse data.
2 types of Interpretation methods
• 1) Comparison of Totals:
– By the use of mathematical functions such as SUM (for the
totals) SUMIF (to total certain cells with specific criteria)
e.g. add all the cells that have a value greater than 11.
– The Use of MAX, MIN
– Look at other mathematical functions such as AVERAGE,
COUNT and describe what it does.
– Think about how we can use these mathematical functions
to analyse data. Example Average can show the average
attendance figures for the whole duration of the course.
Or the average number of sales for a particular item.

2. Trend Analysis:
– One of the tools that we use to analyse trends is by
using the chart functions. This gives us the option to
chose appropriate charts to display our data, so that
is easier to read.
– Think about the charts you have made already for
the attendance register and why you have chosen a
column chart instead of a pie chart for example.
– This would be useful for a summary for example to
show the best week students have come to attend or
to show the number of sales for a particular item
over the month.
D1
To answer this question describe the different
types of mathematical function and the use of
appropriate charts to interpret and analyse
data.

As time is approaching soon towards the end of the
course, the final deadline for all submission of
work is by the 7th of June. This will give ample
time for feedback and for you make changes
accordingly.
Therefore during these holidays you may wish to
visit the website where I’ll upload work for you to
work on and can finish the assignment early as
you wish.
