Data Analysis of the Class Data
• The data must be analyzed with the
purpose of answering the research
question:
– Does placing a seed under the grow light
affect the germination of a __________ plant?
• What can we do with our data to show the
answer to this question?
Excel
• What table or graph should we use to display
our data most effectively?
– It always goes back to the question: Does placing a
seed under the grow light affect the germination of a
__________ plant?
• Tables –
– Format the cells
– Create a table that is easy for the reader to understand
• Graphs –
– Excel data formated for graphing –
• Topics on the first row
• Data under the topic (column)
• After adding your graph to your report, write a
paragraph explaining what your graph shows. No
inferences only facts
Conclusion
Write this in 3 paragraph form:
Paragraph 1
•
Restate Problem – this is the same as the research question
•
Content - what did you learn from the experiment to help you answer the research question?
•
Real world example - How would this be used in the real world?
Paragraph 2
•
Restate Hypothesis – Write your hypothesis here (it does not matter if you were correct or
not, just that you are honest)
•
The hypothesis is – choose either validated or refuted
•
Explain how the evidence validates or refutes the hypothesis – use the data numbers
from your chart/graph to as examples to explain how your evidence validates (matches) or
refutes (does not match) your hypothesis
•
Explain how the evidence answers the problem – use the data numbers as examples to
explain what you did learn from the experiment.
Paragraph 3
•
Error Analysis – Explain what areas of the experiment could have given your class error.
What kinds of things could go wrong in the experiment, based on technique, environment, lab
tools and instruments, or human error?
•
How to Improve Lab – What could we do to eliminate or lessen the errors caused by
technique, environment, lab tools and instruments, or human error?
