Iwill give brainliest to whoever answers all correctly q1: what is an outlier? what is a cluster? q2: how do you determine the equation of a line of best fit for data? q3: explain the difference between frequency and relative frequency.

Ans1.

Outlier

A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.

Cluster

When data seems to be "gathered" around a particular value.

For example: for the values 2, 6, 7, 8, 8.5, 10, 15, there is a cluster around the value 8.

Ans.2

A line of best fit  (or "trend" line) is a straight line that best represents the data on a scatter plot.  

This line may pass through some of the points, none of the points, or all of the points.

i will explain through an example

1.  Prepare a scatter plot of the data on graph paper.

2.  Using a strand of spaghetti, position the spaghetti so that the plotted points are as close to the strand as possible.

3.  Find two points that you think will be on the "best-fit" line.  

4.  We are choosing the points (9, 260) and (30, 530).  

You may choose different points.  

5.  Calculate the slope of the line through your two points (rounded to three decimal places).

6.  Write the equation of the line.  

7.  This equation can now be used to predict information that was not plotted in the scatter plot.

Question: Predict the total calories based upon 22 grams of fat. ANS: 427.141 calories

Ans.3

1.Frequency is the number of times a result occurs, while “relative frequency” is the number of times the result occurs divided by the number of times the experiment is repeated.

2.Frequency can easily be determined by conducting a simple experiment and noting how many times the event in question occurs; no calculations are needed. On the other hand, relative frequency is determined by using simple division.
