Hello!
1. Answer: Well, an outlier is a point that is much different from other points and does not fit the pattern, on a graph it would appear very far from the other points and will just look random or awkward.
2. Answer: Well, If is clear from the scatterplot that as x increases, there is no apparent effect on the y, then we say that no association exists between the variables x and y. So basically if it has no relationship and is all over the place, it has no association. There is no pattern in the points on the scatter plot; there is no pattern of increasing or decreasing when comparing the x- and y-values.
3. Answer: Well, you have to find the given input in the row (or column) of input values. Identify the corresponding output value paired with that input value. Find the given output values in the row (or column) of output values, noting every time that output value appears. Identify the input value(s) corresponding to the given output value.
4. Answer: Well, Conditional frequency is used to examine the relationships between two variables in a two-way table. To find the denominator add all the values in the second (y) column and as seen, that is the denominator for all those values.
I Hope this Helps! Have A Wonderful Day!

1) In a set of data point, an outlier point ( or number) is the number that has an abnormal distance from other values from the set:
Example {23, 34, 54, , 61, 200}, 200 is the outlier
______________________________
| |
------------| 23 34 54 61 |------------200----
|_____________________________|
2) A scatter plot is obtained by plotting x and y of a given function.
Association = Relationship. No association = No relationship.
In short it means if x increase (or decrease) it has no effect on y.
Here below an example of a scattered plot with no association
Y
| * * *
| * *
| * * * *
|__*_________________________x
3) I didn't understand this question. You have many ways to determin the output values example f(x) = 2x, you give x a value and you get y value which is the output value
4) A conditional frequency (or 2 way-frequency-table) is used to study the relationship between 2 categorial variables:
Example:
Math Course Biology Course | TOTAL
BOYS 20 50 | 70
GIRLS 10 70 | 80
-------------------------------------------------------------------------------|----------------
TOTAL 30 120 | 150
To determine which value should be the denominator divide each entry by the total (150 in our example)
Example {23, 34, 54, , 61, 200}, 200 is the outlier
