Title: Confidence intervals
My understanding
I believe my understanding about this topic is fairly good. A confidence interval
measures the amount of error that may occur in a given set of data or the amount of
confidence we have that the data measured wi

Title: Standard Deviation
I would say that my understanding of this could be better. Why is it so necessary to know how
much a data point may or may not deviate from the norm? What is the exact point of it?

Title: Scatterplots
My understanding
My understanding is not very good on this topic. I know that scatter plots are similar to line
graphs and are used to compare data, but how exactly is this done? Are the data points overlaid
to display a more clear cor

Title: Measures of Center
I would say that my understanding of this topic is fairly good. In order to understand any data
set, knowing the center can give you a starting point and help you determine other data points.

Title: Inference for two-way Tables
My understanding
Here we are again comparing two sets of data points, but we are comparing the overall data in
two different formulated tables. But how exactly are the two data sets compared and correlated to
each other
Title: Inference for Proportions
My understanding
The inference of proportions is to compare two data sets of conflicting data, or the different
percentages with a population and a sample. Such as the percentage of those who prefer Pepsi
over coke.

Title: Histograms
I would say that my understanding of this topic is fairly good. Histograms lay out the data in a
chart form so that is more simply viewed and more easily compared.

My understanding
I believe my understanding of this concept is fairly good. In comparing one mean to another we
may ascertain how one set of data may relate/compare to another if they are normally distributed

Title: Census and sampling
I would say that my understanding of this topic is good. Census tell us absolutely about a large
population of people, and sampling allows us to make an estimate about a population without
actually conducting a census, s

Title: Boxplots
I would say my understanding of the topic is fairly good. Boxplots graph the data in a simple
linear line that shows via a box the center of the data set and where the main concentration of
the data points are located, as well as a
