What is a set of data with one variable called?
Univariate.
What does data distribution mean?
It is the set of values that a variable can take together with the probability or frequency distribution for those values.
Is it true that in large data sets the mean is always one of the data values?
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
What is a correlation where one set of data values increases as the other decreases?
one set of data values increases as the other decreases
What is mode in a data set?
Mode is the most common number in a set of data If there are more than one most common number write them all
What a set of data involving one variable?
D
What is a set of data with one variable called?
Univariate.
What is data that can take one value from a finite set of values?
A discrete variable.
Is the value of a variable for an element called data set?
The observed values of a variable form the data set. Not sure where "element" fits into it.
What is a set of data involving two variables?
Bivariate
If the mode of a data set is 35 which must be true about the data set?
35 occurs most often in the collated data set.
Why is a control set up being done in conducting an experiment?
An experiment usually involves a set of steps involving one variable. This is what is being tested. A control involves the same steps without the one variable. The results are checked against each other to see if the variable had any effect.

When looking at data points on a given set of axes which variable is dependent?
The y-Variable
What is a example of discrete data?
Discrete data are observations on a variable that which take values from a discrete set.
WHY is a control setup being done in the conduct of an experiment?
An experiment usually involves a set of steps involving one variable. This is what is being tested. A control involves the same steps without the one variable. The results are checked against each other to see if the variable had any effect.
