It’s not that I’m so smart, it’s
just that I stay with problems
longer.

PerserveranceI've missed more than
9000 shots in my career. I've lost almost 300
games. 26 times, I've been trusted to take the game winning shot and
missed. I've failed over and over and over again
in my life. And that is why
I succeed.

1. Use simple formulae within a spreadsheet.
2. Use basic functions within a spreadsheet.
Lesson Objectives

Spreadsheet Formulae
• You need to be able to use these within a spreadsheet.
• We did this in Year 7 so it should be easy!
Use mathematical operations, for example: add, subtract, multiply, divide, indices
+-
/ *

Basic Formulae
• Always start your formula with an equals sign =
• To add, subtract, multiply or divide you must use cell references
• E.g. =A1 + A2, =C2 – D3, =F5*F6
![Page 6: It’s not that I’m so smart, it’s just that I stay with problems longer. - Albert Einstein](https://reader034.vdocument.in/reader034/viewer/2022050908/56649e625503460f94b5eccd/html5/thumbnails/6.jpg)
Do some *-/+ work!
1. Complete the worksheet you have been given by writing in the formulae you need to use.
2. Open Task 1.xls from the shared area. (Handout > KS4 > iGCSE > Practical Skills > Year 10 and 11 > 14 Spreadsheets > Lesson 1-3 > Task 1
Add the relevant formulae.

Spreadsheets
Functions Putting the FUN back in spreadsheets since 1907!
• How many can you name?
=SUM
=AVERAGE
=MAX
=MIN
=IF
=LOOKUP
=COUNTIF
=SUMIF

Tasks
• You will now be guided through a number of functions by video tutorials.
• The videos will ask you to add functions to a spreadsheet and make written notes.
• The videos are located in – Dept Share > ICT > Handout > KS4 > iGCSE > Year 10
and 11 > Practical Skills > 14 – Spreadsheets > Lesson 1 - Formulae and Functions > Task 2 Videos

=LOOKUP
Some functions use more than one piece of data. They are separated with comas.
=LOOKUP(E6,Tutors.csv!$A$3:$B$12)
Where is the data you want
to lookup?
Where is the table that
contains the results?
![Page 10: It’s not that I’m so smart, it’s just that I stay with problems longer. - Albert Einstein](https://reader034.vdocument.in/reader034/viewer/2022050908/56649e625503460f94b5eccd/html5/thumbnails/10.jpg)
=MAX
=MAX(I6:M6) =MIN(I6:M6)
Which range of cells do you
want to compare?
![Page 11: It’s not that I’m so smart, it’s just that I stay with problems longer. - Albert Einstein](https://reader034.vdocument.in/reader034/viewer/2022050908/56649e625503460f94b5eccd/html5/thumbnails/11.jpg)
=SUMIF
=SUMIF(I6:M6,"<>ABS")
Which range of cells do
you want to compare/use for the sum?
What criteria must be met for it to be included?
![Page 12: It’s not that I’m so smart, it’s just that I stay with problems longer. - Albert Einstein](https://reader034.vdocument.in/reader034/viewer/2022050908/56649e625503460f94b5eccd/html5/thumbnails/12.jpg)

=COUNTIF
=COUNTIF(I6:M6,“=ABS")
Which range of cells do you
want to compare/use for the sum?
What criteria must be met for it to be included?
![Page 14: It’s not that I’m so smart, it’s just that I stay with problems longer. - Albert Einstein](https://reader034.vdocument.in/reader034/viewer/2022050908/56649e625503460f94b5eccd/html5/thumbnails/14.jpg)
ROUND and AVERAGE
=ROUND(A1,0)
=AVERAGE(I6:M6)
Which cell do you want to
round?
To how many decimal places?
Which range of cells should be
averaged?
However…you can use 2 or more
formulae in the same cell. This is
called a nested formula.
![Page 15: It’s not that I’m so smart, it’s just that I stay with problems longer. - Albert Einstein](https://reader034.vdocument.in/reader034/viewer/2022050908/56649e625503460f94b5eccd/html5/thumbnails/15.jpg)
Nested Formulae
=ROUND( =
A1 ,0)
AVERAGE(I6:M6)
![Page 16: It’s not that I’m so smart, it’s just that I stay with problems longer. - Albert Einstein](https://reader034.vdocument.in/reader034/viewer/2022050908/56649e625503460f94b5eccd/html5/thumbnails/16.jpg)
=IF(
• =IF(P6>=$B$3,"Yes","No")
What test do you want to
do? What do you want to
check?
What is entered if the test is true?
What is entered if the test is false?
