MAT 240 Week 1 Discussion | Southern New Hampshire University | Assignment Help
1-3 Discussion: Population, Samples, and Bias
In
real-life applications, statistics helps us analyze data to extract information
about a population. In this module discussion, you will take on the role of
Susan, a high school principal. She is planning on having a large movie night
for the high school. She has received a lot of feedback on which movie to show
and sees differences in movie preferences by gender and also by grade level.
She
knows if the wrong movie is shown, it could reduce event turnout by 50%. She
would like to maximize the number of students who attend and would like to
select a PG-rated movie based on the overall student population’s movie
preferences. Each student is assigned a classroom with other students in their
grade. She has a spreadsheet that lists the names of each student, their
classroom, and their grade. Susan knows a simple random sample would provide a
good representation of the population of students at their high school, but
wonders if a different method would be better.
You can review
the student demographics here: Module One
Discussion Data.
In
your initial discussion post, specifically address the following:
·
Introduce yourself and describe a time when you
used data in a personal or professional decision. This could be anything from
analyzing sales data on the job to making an informed purchasing decision about
a home or car.
·
Describe an example of a sample of this student
population that would not represent the population well.
·
Describe another example of a sample that would represent
the population well.
·
Finally, describe the relationship of a sample to a
population and classify your two samples as random, cluster, stratified, or
convenience.
In
your response posts to at least two peers, discuss the following:
·
Choose two different sampling
methods from among your peers’ responses. Then, identify bias in each peer’s
sample and explain how you think they could remove the bias from their sample.
