Nominal data exercise      Name:____________________

Nominal/Qualitative/Categorical data (freqs,bar graph, Pareto)
https://davidwills.us/stat200/nominalData.html

Copy and paste the birth days data

n=______

Which day has the most births: ____   #___   ____%   the modal category
Which day has the fewest births: ____ #___   ____%

What is the sorting order:_______________ (how is it sorted?)

Write the frequency distribution table, with relative frequencies too.
 In days-of-the-week order. because that's what we're used to.
DAY    #births  RelFreq
---    -------  -------










Look at the Pareto chart.
Sketch it:
Annotate each category's bar with its frequency.














Is it a uniform distribution (i.e. every day equally likely), 
or is there a "pattern" _____________________________________

Partition the data into two categories: weekday and weekend.
Weekday %=________   ==proportion of the data of this combined category
Weekend %=________ 
Think. This can be done with one addition and one subtraction.  

Weekend days are 2/7 of the days of the week, 2/7=______
  hmmm    are the weekend births significantly different from 2/7?  
  Later we will do a chi-squared test of goodness-of-fit to test this. Stay tuned!


Generate a qualitative data set of at least 6 categories of some realistic situation
and totaling at least 30 responses.
Write the frequency distribution table, with relative frequencies too.
 in a meanigful order if possible. because that will aid our understanding of it.
_______      _______     RelFreq
