Planning a Scientific Investigation Flashcards
1
Q
What is a hypothesis?
A
The believed outcome of an experiment
2
Q
What is a null hypothesis?
A
A hypothesis that sates there is no relationship between the variables
3

A
Independent Variable
8
Q
What is the y-axis on a graph?
A
Dependent Variable
9
Q
How is a conclusion written?
A
- Relationship between the variables
L> What correlation? - Are variable’s proportional (straight line)
- Do the results support the hypothesis
10
Q
How is an evaluation written?
A
- Explain the reason for anomalous data
- Suggest improvements to the experiment
- Determine the percentage errors of measuring equipment (is better measurement equipment needed?)
