Task 2

You need to

classify your

print. What type

is it?

Get 2 other

fingerprint

experts to

confirm your

findings.

L/O: Gather and analyse data to find

the mode. (Lvl 4)

Task 3

Add your name to

the class graph.

What is the

modal type of

print? How do

you know this?

L/O: Gather and analyse data to

Ididnt doit

We now know who

didnt do it,

but we still

have suspects. What other

evidence from

the 2 prints

might be

important?

Alert

Mr A Scientist

has a new piece

of evidence

The Prints werewithin 5% of the

mean measurement

between index

finger and

thumb..


20/32

So what..?

What should we

do next?

How can we

calculate whatis necessary?

L/O: I can use the mean to identify relevant

data



21/32

The Mean

The mean is

calculated by

adding all the

data up, thendividing by how

many pieces of

data you started

with.

L/O: I can use the mean to identify relevant data (Lvl 5)


22/32

5%

5% of somethingis easy

Divide by 10,

then half!

Example:

12cm

12cm/10=1.2cm Half of 1.2cm is0.6cm

L/O:I can calculate a percentage (Lvl 5)
