WK3 original assignment to be used – if an ANOVA is used, must conduct and
report a tukey post-hoc test
Student Request: Looking for assistance in answering
all the inquiries below, but also assistance on instructions to go by in the
future on how to derive at the answers so I can practice putting them in
myself. While I need to the tables plugged in throughout the assignment, I
need to be able to run through the SPSS software so I know also how to do it,
so in the future I can apply in my future lab assignments as I am new to the
software.
QUESTION 1
Describe the sound, environment, and test score variables.
You should generate frequency tables and bar charts for the nominal variables.
Generate and interpret descriptive statistics of central tendency for any
continuous (scale) variables and include histograms with the normal curve
superimposed for each scale variable. Label your tables and graphs according to
APA format. Conclude with a paragraph summarizing this data.

Analyze whether test scores
has any significant outliers. Write up your conclusion (using stats and a
figure to back up your conclusions). Report what you would do if you do find
