Coincidentally, I've been looking at some data in
our help desk database. I'm considering a creation_date
column in the table which holds open and closed
cases as a possible candidate for a histogram.
Cases seem to come in at a fairly even rate. We open
something like 5,000 to 10,000 per month for the last
year or so. About as many cases are opened any
day of the month (about 500 per day) except for weekends
and holidays when 0 cases are opened.
My question is this: In general, this data appears to
be fairly well-distributed. However, does the fact that
for each Saturday and Sunday there are zero rows
mean that this data is skewed? Might this column be
a good candidate for a histogram?
Thanks,
