A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How does the outlier affect the mean of the data?

An outlier does affect the mean of the data. How it's affected depends on how many data points there are, how far from the data the outlier is, whether it is greater than the mean (increases mean) or less than the mean (decreases the mean).

How does the outlier effect the data?

Outlier: an observation that is very different from the rest of the data.How does this affect the data: outliers affect data because it means that your calculations might be off which makes it a possibility that more than the outlier is off.

What is the effect of the a small outlier value Will it affect of a data set?

No. The data set will remain the data set: they are the observations that are recorded.

How does the outlier affect the median?

Outlier does not affect the median.

How does the outlier affect the range of a data set?

Range subtracts the lowest value from the value in your data set. If you have an outlier, meaning a number either obviously outside the data, your range will be incorrect because one of the values will not represent the average pattern of the data. For example: if your data values include 1,2,3,4,and 17, 17 would be the outlier. The range would be 16 which is not truly representative of the rest of the data.

What is the outlier in this set of data 10064635862?

there is no outlier because there isn't a data set to go along with it. so theres no outlier

How would the outlier affect the mean and median of the data?

An outlier will pull the mean and median towards itself. The extent to which the mean is affected will depend on the number of observations as well as the magnitude of the outlier. The median will change by a half-step.

Given the following data 164 175 126 135 159 143 55 what effect will the outlier have on the median of the data if the outlier is excluded?

If the outlier is excluded the median of the data will be higher.

If you take off the outlier does it make the mean change?

Yes, it will. An outlier is a data point that lies outside the normal range of data. This means that if it is factored in the mean will move in the direction the outlier is, really high if the outlier was high, and really low if the outlier was low.

How does outlier affect mean median mode?

An outlier pulls the mean towards it. It does not affect the median and only affects the mode if the mode is itself the outlier.

What do you take if there is an outlier in data?

If a data set has an outlier, you would normally deal with it by omitting it from the average of the other values.

What is an outlier and what central tendency is affected always by an outlier?

An outlier is a number in a data set that is not around all the other numbers in the data. It will always affect the average; sometimes raising the average to a number higher than it should be, or lowering the average to something not reasonable. Example: Data Set - 2,2,3,5,6,1,4,9,31 Obviously 31 is the outlier. If you were to average these numbers it would be something greater than most of the numbers in your set due to the 31.

How do you get an outlier?

the most common cause of an outlier is an error in the recording of data.

What is the outlier in this data base 91232811?

A single observation cannot have an outlier.

How does a outlier look like in math terms?

An outlier looks like a piece of data that does not fit the pattern of most of the data. However just because some data point "looks like an outlier" does not necessarily mean that it is - standards for deciding whether something is an outlier or not varies a lot from course to course (and how accurate you want to be), so one person's outlier is another persons normal data.

Can you have more than one outlier in a set of data?

Yes, any data point outside thestandard deviation its an outlier

A data value that is much higher or lower than any other data values in a set?

the data value that is much higher or lower than the other data given is called an outlier

What does anomalous data show on a graph?

An Outlier; an Outlier is when a point is not part of a trend (pattern)

Can there be more than one outlier in a set of data?

Yes there can be more then one outlier

How does an outlier in a group of numbers affect the mean of the numbers?

The outlier skews the mean towards it.

What is the outlier of this data 615182021222425282930?

i can not tell you need to space it out and to find outlier try using a box and whisker plot. and if it is just one number there is no outlier

What is data instance that is not typical for a given set of data?

An outlier.

What is A piece of data that is quite separated from the rest of the data?


How does the outlier affect the mean median mode?

An outlier can increase or decrease the mean and median It usually doesn't affect the mode

Explain the difference between the range and the outlier?

Range is the largest minus the smallest value in the data set. An outlier is a value that is far away from the majority of the data.
