What the definition for Arithmetic Sequence?
A sequence in which a constant (d) can be added to each term to get the next term is called an Arithmetic Sequence.
what the definition for domain and range?
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

what is Mean?
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

what the definition of Causation?
A scatterplot displays data about two variables as a set of points in the x y xy xy -plane and is a useful tool for determining if there is a correlation between the variables. Causation means that one event causes another event to occur. Causation can only be determined from an appropriately designed experiment.
what are disadvantages of box plot?
Not as visually appealing as other graph.
Exact value not retained.

Causation
what is Median?
Median The middle number found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).

what is a function for negative?
is when the graph below the x-axis.
what the definition of Correlation?
Correlation refers to the degree of correspondence or relationship between two variables. Correlated variables tend to change together. If one variable gets larger, the other one systematically becomes either larger or smaller.
what are the advantages for box plot?
Shows 5-point summary and outlier.
Easily compares two or more data sets.
Handle extremely large data set easily.
