I've shown you three different modes of communicating information.
how we use statistics very often to convey information.
that is contained in the data so that we can communicate the most important information.
we can communicate important information that is contained in the data.
For instance, very often, we use averages.
And we say, the average of this or the average of that.
very often, numbers are provided in form of statistics.
information and remove a lot of details.
which is this image that you have in front of you, these four plots.
So, let me describe to you these four plots and what they mean.
we have four different datasets.
Y4), four different datasets represented in four different scatter plots.
these four scatter plots have very different patterns.
we realize that they have exactly the same numbers.
exactly the same average of Y.
They have exactly the same linear interpolation, and so on.
many cases, that are exactly the same.
we can readily perceive information that is hidden in the statistics.
So, that's a very important concept and idea to keep in mind.
