Question

Given a scenario describe a "research question" with an implied population, implied sample, a given parameter - What is the best way to help students identify: Population, parameter, sample, statistic, variable, and data...

Answer #1

(a) Research Question: What is the average height of a student in your college?

(b) Implied population: All the students in your college

(c) Implied sample: All the students in your class

(d) a given parameter : Height of a sdudent in your college

BEST WAY TO HELP STUDENTS:

Your research question is to find the average height of a student in your college. Since the population size = N is very lage, you consider the students in your class as a sample.

n = sample size = number of students in your class

= sample mean -= average height of a student in your class

Here:

Sample statistic = sampls mean

Population parameter = Population mean

Variable = height of students

data = values of the heights of students

Use the words relationship, sample, population, statistic, and
parameter to describe the flow of a research study to determine
whether a relationship exists in nature.

Using key terms, create a scenario where you can find a
population, a sample, the
parameter, the statistic, a
variable, and data. Post your
scenario and provide a detailed description using the key terms.
After reviewing the information, what did you learn about your
target population?

Confidence intervals seek to estimate a population parameter
with an interval of values calculated from an observed sample
statistic. Demonstrate that you understand this concept by
describing a situation in which one could use a sample mean or
sample proportion to produce a confidence interval as an estimate
of a population mean or population proportion. I am asking you to
make up a situation where a confidence interval might be computed.
Clearly identify the population, sample, parameter, and statistic
involved...

. Describe the difference between a "population" and a "sample."
What is a "representative sample"? What is the best way to achieve
representativeness in a sample?

Describe the population and , if relevant, the sample. For each
number presented, determine if it is a parameter, statistic, or
something else and explain why. (a) A survey of 2000 college
students finds that 36% watch the TV show "Game of Thrones." (b)
The 2010 US Census reports that 13.9% of the US population was
between the ages of 15 and 24 years.

Create and describe 3 scenarios in which you then identify (for
each scenario), (a) the population and (b) the sample.

Research question: Amongst all Penn State students, do
traditional-age students and adult learners differ in terms of
their grade point averages (GPA)?
Researchers are going to collect data from 1,000 Penn
State students. They will call each student to ask whether they
identify as a traditional-age student or as an adult learner. They
will also ask each student for their GPA (scale of 0 to
4.0).

could use a convenience sampling method to obtain a sample...
