If a related measures experiment and matched subject experiment both produce t statistics with degrees of freedom of 20 which experiment used more subjects?
The matched subject because the experiment involves pairs which halves the df.
What is a factor that can have more than one value?
A variable
Which is bigger 10 kilo or 10 miles?
Neither. They are measures of different things Kilos or kilograms are measures of mass. Miles are measures of linear distance.
Does mean median or mode best describe a data set?
Each of these measures of central tendency has its own advantages and disadvantages. Different measures are best in different circumstances.
For what purpose multivariate analysis is used?
Used when you have an experiment with several related dependent measures. Also used to analyze data from a within subject design.
Does A controlled experiment measures the effect of one variable?
Yes, that's the precise definition of a scientific experiment.
If a related measures experiment and matched subject experiment both produce t statistics with degrees of freedom of 20 which experiment used more subjects?
The matched subject because the experiment involves pairs which halves the df.
Can a study have internal validity but not external validity?
Yes. Internal validity is whether or not the experiment is studying what it intends to. External validity is whether or not the study can be generalised outside of the study. For example, if you had a perfect experiment set up, that measures something perfectly, then it will have internal validity. You haven't, however, shown that you would get the same results in different cultures, or in different time periods. Thus the experiment may not have external validity.
Safety measures to follow during a experiment?
When performing an experiment you want to be sure you are following precaution. You should wear safety goggles, protective clothing and gloves.
Is controlling variables a controlled experiment?
an experiment to test a scientific hypothesis in which the variable component is controlled, not random, eg In an experiment that measures volume vs time to boiling, the volume, being the indirect variable, is measured.

What is a factor that can have more than one value?

Mike is doing a laboratory experiment The experiment's materials list says that Mike needs to have a balance What will Mike most likely need to do during the experiment?
He most likely Mike will have to measure or compare the masses of some objects. MIKE HAS HUGE OBJECTS THAT HE MEASURES EVERY NIGHT . HE HAS MEASUREMENTS IN YOUR MOMMYS MOUTH AND HE PUTS IT IN TO SEE HOW DEEP IT WILL GO..THATS HOW MIKE MEASURES HIS OBJECTS
How much is it for health insurrance?
different places may have different measures.
Congruent angles have different measures?
False
How are a cylinder and a different?
They are two different ways of measuring. A balance measures weight (or technically, mass) while a graduated cylinder measures liquid volume.
