How does the outlier affect the median of this data?
An outlier is 1.5 times the mean, when you are taking an average it may give an inaccurate representation of the data. It usually does not affect the median.* * * * * The above definition of an outlier is total rubbish! It is necessary to have a measure of the central tendency (mean or median) AND spread (standard deviation or inter quartile range - IQR) to define an outlier.If Q1 and Q3 are the lower and upper quartiles, then outliers are normally defined as observations lying below Q1 - k*IQR or above Q3 + k*IQR. There is no universally agreed definition of outliers and hence no fixed value for k. But k = 1.5 is often used.
How do you measure for mulch?
Measure the length,width, and depth of the are you want to spread the mulch.
What is strandard deviation?
It is a measure of how much individual values spread around the average.
What does a probability distribution with high variance indicates?
There are several things that will cause a large variance. One would be a large spread in the data; the other is the data may contain an outlier(s) that is causing it or a combination of both.
What is the definition of spread math?
Spread, in the context of a probability distribution, is a measure of how much the data vary about their central value.
Why do we need the standard deviation?
The standard deviation is a measure of the spread of data.
Why is calculating the standard deviation an important part of data analysis?
It is a measure of the spread of the results around their expected value.It is a measure of the spread of the results around their expected value.It is a measure of the spread of the results around their expected value.It is a measure of the spread of the results around their expected value.
What do scientists think led to the vast variation seen in flowers?
The spread of pollination.

Why does the standard deviation get smaller as the individual in a group score more similarly on a test?
Because the standard deviation is a measure of the spread in scores. As individuals score more similarly, the spread gets smaller. Because the standard deviation is a measure of the spread in scores. As individuals score more similarly, the spread gets smaller. Because the standard deviation is a measure of the spread in scores. As individuals score more similarly, the spread gets smaller. Because the standard deviation is a measure of the spread in scores. As individuals score more similarly, the spread gets smaller.
What standard deviation tells us about a distribution?
It is a measure of the spread of the distribution: whether all the observations are clustered around a central measure or if they are spread out.
How do you measure for mulch?
Measure the length,width, and depth of the are you want to spread the mulch.
Will a 4-inch centered faucet fit a 4-inch centered hole when the specifications state that the spread between the two faucets is 4 and three quarter inches?
4 inch center the 4 3/4 spread is the distance outside to outside the sink will more then likely measure 5 inch spread in not more
How do you stretch for center spilts?
spread ur legs
What is the s d?
Standard deviation (SD) is a measure of the amount of variation or dispersion in a set of values. It quantifies how spread out the values in a data set are from the mean. A larger standard deviation indicates greater variability, while a smaller standard deviation indicates more consistency.
What is strandard deviation?
It is a measure of how much individual values spread around the average.
