How To Make a Data Table

In Science

Variables

Your data table will include your manipulated variable (the “If” from your hypothesis), your

responding variable (the “Then” from your hypothesis) and quantitative data.

Quantitative data is measurement, when you use numbers to describe something. Examples: measuring length, mass, force, (weight), volume, speed, time, etc.

For example you might experiment to see if increasing the fertilizer you add to your pumpkin

plants will make your pumpkins grow larger.

Your hypothesis might look like this:

If I increase the number of times I fertilize my pumpkin plants from once

a week to twice a week then my pumpkins will grow heavier by the end

of the growing season because they will be healthier and grow faster.

Your experiment should include those pumpkins that get fertilized once a week and those that get fertilized twice a week so you can compare their growth. The more data you collect, the more proof you will have to support your hypothesis

If you had a nice big garden, you could plant 6 pumpkin vines (3 that get fertilized once a week and 3 that get fertilized twice a week) to grow

your pumpkins and collect data.

First step is to name your graph

Pumpkin Growth With Increased Fertilizer

Second step is to add your Manipulated Variable

Pumpkin Growth With Increased Fertilizer

FertilizedOnce Weekly

Fertilized Twice Weekly

Third step is to add your Responding Variable

Pumpkin Growth With Increased Fertilizer

Weight of pumpkins in kg

FertilizedOnce Weekly

Fertilized Twice Weekly

Fourth step is to add your Data Table

Pumpkin Growth With Increased Fertilizer

Weight of pumpkins in kg
