Data Analysis
Given the following students’ test scores (95, 92, 90, 90, 83, 83, 83, 74, 60, and 50), identify the mean,
median, mode, range, variance, and standard deviation for the sample.
Write a 500-750-word summary and analysis discussing the results of your calculations.
State your results for the sample: the mean, median, mode, range, variance, and standard deviation
1.Explain which method is best for this data set. Why?
2.Conduct a one sample T-test and interpret the results (use a population mean of 70).
3.In what situations would this information be useful?
Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student

Data Analysis
Unsatisfactory (0.00%)
Identification of the mean, median, mode, range, variance,
and standard deviation for the sample given is missing.
Explanation of which method is best for the data set and why
is missing.
Interpretation of results and what situations would the
results be most useful are missing.
Paper lacks any discernible overall purpose or organizing
claim.
Paragraphs and transitions consistently lack unity and
coherence. No apparent connections between paragraphs are
established. Transitions are inappropriate to purpose and
scope. Organization is disjointed.
Surface errors are pervasive enough that they impede
communication of meaning. Inappropriate word choice
and/or sentence construction are used.
Template is not used appropriately, or documentation format
is rarely followed correctly.
Sources are not documented.

Less than Satisfactory (65.00%)
Identification of the mean, median, mode, range, variance,
and standard deviation for the sample given is vague and
inconsistent.
Explanation of which method is best for the data set and why
is vague and inconsistent.

results be most useful are vague and inconsistent.
Thesis and/or main claim are insufficiently developed and/or
vague; purpose is not clear.
Some paragraphs and transitions may lack logical progression

of organization is evident.

formatting errors.
