An outlier will affect the measure of center, such as the mean, median, or absolute mean deviation.
Answer:
True
Step-by-step explanation:
Outliers still are apart of the data, so it will effect the overall measurement because it is different from the other data collected.

I need an answer to this question
Answer:
d company 4
Step-by-step explanation:
given that there is one possible outlier. if the outlier was removed from the data set, how would it effect the measures of central tendency? {8, 73, 74, 75, 79, 85, 85, 92, 94}
(not links)
O Mean increases median decreases
O Mean decreases median increases
O Both mean and median increase
O Both mean and median decrease
Answer:
Some measures I believe you are talking about are mean, median, mode, and range.
Mean is the average of all values. This is found by adding up all numbers and dividing by the amount of numbers. Outliers greatly affect and "throw off" the mean, making it inaccurate at calculating the average without an outlier.
Example:
1, 2, 4, 6, 10
(1 + 2 + 4 + 6 + 10)/5 = mean = 4.6
1, 2, 4, 6
(1 + 2 + 4 + 6)/4 = mean = 3.25
Because of this, mean does change when adding and removing outliers, and is therefor not the answer.
Median is the middle of the data. This is found by ordering the values in the data set from least to greatest (or greatest to least, either one works) and finding the number in the center of all the values. If there were an outlier, the median wouldn't be skewed as the mean is by outliers, but it would change.
Example:
1, 2, 4, 6, 10 Median = 4
1, 2, 4, 6 Median = 3
So median is not the answer, because it is affected by adding and removing outliers.
Mode is the value in a data set that appears the most. Outliers are numbers that are significantly lower or higher than most or all of the other numbers in a data set. Because of this, there can't be more outliers than other numbers, so it is impossible for the mode to be an outlier.
Example:
1, 1, 1, 2, 3, 4, 4, 86 Mode = 1
1, 1, 1, 2, 3, 4, 4 Mode = 1
This means the mode is not affected by adding and removing outliers.
Mode is a possible answer, but let's take a look at range before coming to a conclusion.
Range is the spread of values in a data set. In other words, the difference between the highest and lowest value. A high range can signal a possible outlier is present.
Example:
1, 2, 4, 6, 10
10 - 1 = highest value - lowest value = range = 9
1, 2, 4, 6
6 - 1 = highest value - lowest value = range = 5
The range is certainly affected by outliers, so it is not the answer.
Out of mean, median, mode, and range, the answer to this question is mode.
If an outlier is removed, mode will not change.
Hope this helps!

Determine the measures of the angles if they are both vertical and supplementary.
Answer:
90, 90
Step-by-step explanation:
Since the two angles are vertical, it means that they must have the same measure. Because they are supplementary, that means they add to 180. Thus, the two angles must be 90 and 90.

Tonya sampled 35 customers leaving the grocery store to find out how long they spend shopping. The results were that two people spent less than 15 minutes shopping, 28 people spent between 15 minutes and an hour shopping, and five people spent over an hour shopping.
Inference: Most customers spend less than an hour shopping.
Defend or challenge the inference with at least two complete sentences.
Answer:
challenge because it said 28 people spent between 15 and an hour if that is so the could have been there for an hour so there
Step-by-step explanation:
Answer:
The inference makes an incorrect statement.
Step-by-step explanation:
It is said that Tonya sampled 35 customers, where 28 of them spent 15-60 minutes, and 5 people spent over 60 minutes. This means that there are already 5 people that shop for over an hour. There may also be a bigger portion of shoppers that shop for exactly 60 minutes (1 hour), which is NOT less than 1 hour.
Hope that this helps! :)
During each of the first three quarters of the school year, Melissa earned a grade point average of 21, 29. and 31
What does her 4th quarter grade point average need to be in order to raise her grade to a 3.0 cumulative grade
point average?
A 3.9
B. 4.2
C. 2.6
D. 3.5
Answer:
A. 3.9
Step-by-step explanation:
If Melissa scores a grade point average in the fourth quarter of 3.9, the the sum of all of her grade point averages would be 12, and that divided by 4 would make the average 3, giving her a grade point average of 3.

Which is NOT a line of symmetry (please help)
Answer:
3
Step-by-step explanation:
The line 3 is not a line of symmetry.
What is Line of Symmetry?Line of symmetry of a figure or a shape is the line which divides the figure or shape in to equal and symmetrical parts.
This line is also called as axis of symmetry.
It is sometimes also called as mirror line since the line divides in to parts which looks like mirror images.
Given is a shape of a triangle.
There are 4 lines drawn.
Of these, 3 lines are drawn from a vertex of the triangle to the middle point of the opposite side, which divides the triangle in to two equal triangles.
So these lines are lines of symmetry.
But line 3 does not divide the triangle in to equal parts.
So it is not line of symmetry.
Hence line 3 is not a line of symmetry.

help and explain how you got the answer
pls give an actual answer
Answer:
Part A:
mean: 4.7
median: 4.5
mode: 6
The range is 10 so i think in this situation the variability is high becaue 10 miles is a lot more than 2 miles or 0 miles
Part B:
No, even though the mode is 6 it makes more sense to use the medain or mean to get as close as posible to about how much she rides each day

Not drawn to scale
a. * = 12
b. x =18
0.
36
d x = 54
Answer:
I believe x = 12
Step-by-step explanation:
If the triangles were similar then they would have the same angle measures.
Steps:
Add angle K and L: 90 + 54 = 144
Subtract the added angles from 180 to find angle J: 180 - 144 = 36
Angle J is similar to angle X so, divide 36 by 3: 36/3 = 12
x = 12
