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
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

Title: Inference for Proportions
My understanding
The inference of proportions is to compare two data sets of conflicting data, or the different

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 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

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: 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?
