How do you graph outliers on a box plot when given a data set of
numbers? I found the median, lower and upper quartile numbers and
have already plotted that but how do you plot outliers?
Lets say the data is :1 2 3 4 5 6 7 8 9

In Nonlinear regression analysis, if we have a data set and if
we need to model nonlinear, once we enter the data either in R or
SPSS software we observe the results, but we cannot see the exact
equation as we can write for linear regression.as an example if we
want to see the relationship between Sales the response variable
and the advertising budget for TV media and News paper we have to
independent variables,once the data we entered how...

When calculating variance, we square the difference between each data point and the mean in a set of numbers. Why do we do this?
When calculating variance, we square the difference between each
data point and the mean in a set of numbers. Why do we do this?A. The deviation scores will sum to zero and cancel each other
out if they are not squared first.B. We need to even out the numbers to make them easier to
handle.C.Squaring the difference between a data point and the mean is
the way to calculate deviance.D. Larger numbers are easier to calculate than smaller
numbers.
