Biodiversity Graphing LessonSetting up Axes

Step # 1:  Look at the Manipulated

Variable (MV )Data

Which is the MV?

Height ?

or Arm Span?

Step # 2 Put the data numbers in order,

smallest to largest:

Step # 3 Find the minimum (smallest

number in the set of data) minimum

Step # 4

Find the maximum (largest number in the set of data)

maximum

Step # 5

Find the RANGE

Equation: Maximum - Minimum = RANGE

This is the DISTANCE from (maximum) to

(minimum) on the

axis.

Step # 5 Continued MATH!

is the RANGE !!!

Step # 6 Look

at the graph paper

Step # 6 Continued

Count the # of boxes from side to side (across or HORIZONTALLY)

Step # 7Divide the RANGE by the number of boxes from step # 6

MATH!

.8

Step # 8

Round this number (.8) up

.8 … .9 … 1 !!

Step # 9 Each box on the X axis shows 1

X Axis

Step # 10 Put the minimum on the first

line:

minimum 

Step # 10 Continued Continue labelling lines (adding 1 each time), until you get to the maximum or

the first number over the maximum l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l_l1   2   3  4   5   6   7   8   9  10 11  12  13  14 15  16 17 18  19 20 21  22 23 24 25

minimum maximum

Step # 11

Put a dot

on the axis to mark where each of your DATA numbers would be.

Repeat all the steps with the Responding Variable (RV)
