Create a graph (either a histogram, box plot or stem and leaf
plot … pick just one). Your graph could have either 5, 6 or 7
classes, depending on how you set it up. Create a table and list
the class boundaries and the frequency in each class. You must
explain to me in detail if you used fewer than 5 classes or more
than 7 classes.
a) Make a frequency distribution table.Make a frequency
distribution table with 6 classes on the following test scores of
25 students in my class. Include the following columns in the
table: Classes, Frequency, Class Mark, Class Boundaries, Relative
Frequency and Relative % (make sure you find the class width) 45,
67, 87, 96, 76, 56, 45, 56, 67, 77, 88, 92, 34, 37, 46, 86, 90, 96,
49, 50, 60, 70, 85, 70, 99
b) Use the test scores in...
6. Histograms:
a) How is the histogram related to the frequency plot?
i. When does a histogram look exactly like a frequency plot?
b) What visual information do you get from a histogram?
c) How can you tell what interval contains the most data
points?
d) What is the relation between histograms and the cumulative
distribution function?
e) The probability of winning at American roulette is 1/38

a) Use the Histogram tool to develop a frequency distribution
for the number of days and the browser used as a customer of this
online store. Use your judgement for determining the number of bins
to use.
b) Construct complete histogram graphs and numerical
descriptions (that is, histograms and measures of location and
dispersion) for the length of time the shopper spends on the
website and the amount spent per transaction.
c) The company would like to investigate the effect...
