Construct a histogram on StatCrunch , choosing Frequency under the Type drop-down menu. Let StatCrunch
decide upon the number of bins. Leave that field blank. Be sure to name the histogram and to label the axes.
Copy and paste your histogram here:
a) Is the distribution symmetric or skewed? Explain
b) Is the data concentrated in one or two bins or is it evenly spread? If it is concentrated, what bins are the
areas of concentration? Does this seem to characterize a “typical” value? Explain your reasoning.
3.
Write a brief description of the distribution you created, describing its shape, center, and spread.
4.
Now create another StatCrunch histogram, but this time let the bin width = 3. Describe how this new histogram
differs from your first one. Describe its shape, center, and spread.
5.
Experiment with two other bin widths and describe the histogram created with each.
