What is the name of the dataset?
The Name for the dataset is garbage.
What does each observation (row) in the dataset represent?
The rows show the number of people in the household that is
observed.
Each dataset is a sample from a population. What populat
The variables being compares are education level, unemployment rate, and median weekly earnings. I
think this graph is not misleading but inaccurately labeled. You can easily miss the labels in the middle.
At first glance, this looks like an unemployment

In this unit, you will investigate the normal probability curve (the bell curve). Many variables,
such as height and weight are normally distributed. This means, for example, that if you were
to collect 10,000 female adult human heights, the histogram of
In Unit 5, there are three main topics (problem types): describing correlations, measuring
correlations, and evaluating here scatterplots. You will be exposed to all three topics by either
formulating a response (main post) or commenting on a classmates r
During Unit 8, you will learn about how to use a sample statistic (such as a sample mean) to
estimate the value of a population parameter (such as the true population mean). For example,
you can estimate the true mean weight of all newborn babies in the e
During this unit, you will learn about many different types of graphs, which graphs are
most appropriate for specific data, and when graphs are misleading. For instance, a
graph can misrepresent the data if it does not provide a proper representation of t
Bennett, Briggs, Triola (12/2012) accentuates that a normal distribution can have any value for the mean and any
positive value for the standard deviation. Therefore, this explains why results for GMAT, the LSAT, and the GRE
test are normally distributed
According to Bennett, Briggs, and Triola (2012), theoretical probability is primarily based on the
assumption that the likeliness of an event occurring is based on all the possible outcomes. In my

A population parameter is a characteristic that describes a population (Bennett, Briggs, Triola, 2012), but
its often impossible or difficult to know its actual value mainly due to sampling errors, especially when
dealing with a large population. Its also

especially when it comes to reproducing and discussing the presented information in words. However, graphs should
