|
What is an anomalous result |
Odd or an outlier |
|
|
What is the range |
The minimum and maximum |
|
|
What the gap called between each value called? |
The interval |
|
|
How could a preliminary experiment help you decide a control variable |
Determined the upper and lower range |
|
|
How to deal with anomalous results |
Reject them |
|
|
What is a control variable |
Kept constant |
|
|
Concentration on a reaction what could be control variables |
Temp, volume , mass , metal |
|
|
What is resolution |
Smallest scale division |
|
|
Advantage of comparing results |
Check results confirms ur experiment is reproducible |
|
|
What is a variable |
A factor that can be changed |
|
|
What's a repeatable experiment |
An experiment that gives the same results |
|
|
What is a reproducible set of results |
Same results no matter who completes it |
|
|
Usually on a graph which are X and y |
Usually X is independent and Y is dependant |
|
|
What is a dependant variable |
Measured results of the experiment |
|
|
Making and experiment valid |
Change only one variable and keep others constant |
|
|
Differences between Dependant Independent |
Independent- are changed by the experimenter according to plan
Dependant- measured by the experimenter |
|
|
Common error |
Zero error Temperature Measuring Weighin |
|
|
What is a fair test |
An experiment in which only the independent variable affects the dependent variable |
|
|
What name is given to the standard procedure to lower hazards |
Risk assessment |
|
|
What is a control variable |
Kept constant |
|
|
Why would I take more readings |
To change the interval To change the minimum and maximum Allow a mean |
|
|
Ensure valid results |
Actually measuring accurately Keep variables constant Make sure there repeatable |
|
|
How would you choose a suitable interval |
It should allow a pattern to be seen |
