Does removing an outlier increase standard deviation?

Mathematics
1 answer:
horsena [70]1 year ago

Yes, If there are any outliers in the data set, the standard deviation will be large since the deviation from the mean will have increased. Therefore, if the outliers are eliminated, the standard deviation will be reduced, probably reflecting the true features of the population.

The impact on the standard deviation increases with the outlier's extremeness. Outliers make your data more variable, which reduces statistical power. Therefore, eliminating outliers can make your findings statistically significant. A removal of an outlier will have an impact on the mean. The standard deviation will decrease if the outlier was larger than the mean.

The standard deviation will increase if the outlier was less extreme than the mean. It's best to get rid of outliers only when there's a good cause to. Some outliers in your dataset represent normal population variance and ought to be left alone. They are referred to as real outliers.

3/5 + 1/5 pls help meee
Alik [6]

Answer:

\frac{3}{5} +\frac{1}{5} =\frac{4}{5}

Step-by-step explanation:

The denominator doesn't really matter here. You just have to add the numerators and then put the denominator back on again. The numerators are 3 and 1 and if you add 3 and 1 you will get 4. Now you have to put the denominator back on to the bottom of the numerator. So, if you but 5 on the bottom of 4 it will be \frac{4}{5}.

A can of soup has a radius of 6 inches and a height of 10 inches. How much soup can fill the can if it is filled to the top? Pla
denpristay [2]

A can of soup is a cylinder. We want to know how much soup can fill the can, which means that we are looking for the volume.

Formula for the volume of a cylinder: V = pi x r^2 x h

V = pi x 6^2 x 10

V = pi x 36 x 10

V = 360pi inches^3

Hope this helps! :)

FASTEST ANSWER WITH STESP FOR PROOF GETS BRAINLIEST
bogdanovich [222]

Answer:

314.16 m (if pi = 3.14) || 314π m (if (you may want to check the math yourself, just in case!)

Step-by-step explanation:

Step 1) Formula of a cone.

•volume = (1/3) * π * r² * h. [Or, if you prefer, volume = π * r² * h/3 ]

Step 2) Apply numbers.

•r = 1/2 * base diameter || r = 5 m

•height(h)= 12 m

Step 3) Apply formula.

V= (1/3) * π * 5² * 12

[Step 4 depends on how you learn, and this also dictates the answer, please read carefully.]

Step 4a) IF DEFINITE EXACT ANSWER (π = π), then V= 314.16

Step 4b) IF π = 3.14, then V= 314π

I was taught in a strange way where two different methods can be applied, so the answer depends on which one you've been taught!

(apologies if a mistake has been made)
