Nominal data exercise Nominal/Qualitative/Categorical data (freqs,bar graph, Pareto) https://davidwills.us/stat200/nominalData.html Copy and Paste the birth days data n=______ Which is the modal category (has the biggest count) Which day had the most births: ____ #___ ____% the modal category Which day had the fewest births: ____ #___ ____% What is the sorting order:_______________ (how is it sorted?) Look at the Pareto chart. Write the frequency distribution table, with relative frequencies too. Maybe in days-of-the-week order? because that's what we're used to. DAY #births % --- ------- --- 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 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 a chi-squared test of goodness-of-fit to test this.
