What do you need in a discussion
Results show
Supports/ doesn’t hypothesis that says…
Explain (using science) what this means/why it happened
Valid?
Reliable?
Future studies
what are secondary sources?
published sources of information
What is the CRAAP test
Currency-date of publication
Relevance- does it fit the needs
Authority-is the source of reliable
Accuracy-does it agree with other sources
Purpose-is it free of opinion
what is a mistake
That can be avoided with care taken.
Occurs when experimenter does something incorrectly.
What is an error?
It happens due to limitations in how measurements are taken.
What is a parallax error
Look at scale from wrong angle.
What is a reading error?
Scales hard to read accurately if marks a faint or too close together.
What is a instrument error?
The tool that the experimenter is using is not perfectly made or has more thoughts.
What is the human reflex error
When measuring things that require reaction different human reaction times can cause small errors.
What is 0 error
When measuring tool does not start exactly from 0
What is margin of error?
Used to show a range in which the true value may lie. Often used when it is difficult to get an accurate reading of results it’s represented by +
-
What is data?
Classified by where you obtain it.
First-hand / primary data=own experiment
Second-hand/secondary data = other people’s work.
What is the systematic error
Tools / equipment
What is random error?
Human
How do you make a table of data? (tabulating data)
Iv=left
DV=right
units of table=heading ONLY
use ruler and PENCIL
What is reliability?
Data is only reliable if a variation of values is small.
Repeating lets us test the reliability of data.
How do you draw a graph?
IV=x axis
DV=y axis
TUPAC
PENCIL AND RULER
What is a column graph?
Discrete data.
IV has categories not numbers.
What is a line graph?
Continuous data.
IV has numerical data.
