Organizing Qualitative Data

What are the three ways to organize data?

• Tables, graphs, and numerical summaries

• Frequencies, titles, and percentages

• Qualitative, discrete, and continuous

• Charts, pictures, and numerical summaries

What is a frequency distribution?

• A distribution that lists each category of the data and the number of occurrences for each category

• A list of all the outputs for a statistical variable

• A list of all the frequencies of a quantitative variable

• The discrete inputs for designed experiment

How is a relative frequency calculated?

• By dividing the frequency of a category by the sum of all frequencies

• By dividing the frequency of a category by the total number of categories

• By dividing the sum of all frequencies by the frequency of a category

• By dividing the total number of categories by the frequency of a category

What is a bar graph (plot) used for?

• To display the frequency or relative frequency of each category of the data

• To display the proportion or percentage of observations within each category

• To display the differences between groups of data

• To display the relative importance of differences between groups of data

What is a Pareto chart?

• A bar chart where the bars are drawn in decreasing order of frequency or relative frequency

• A bar chart where the bars are drawn in increasing order of frequency or relative frequency

• A pie chart where the sectors are drawn in decreasing order of frequency or relative frequency

• A pie chart where the sectors are drawn in increasing order of frequency or relative frequency

What is the 80/20 Rule or Pareto Principle?

• The majority of the results (frequencies) come from a minority of the inputs (categories)

• The majority of the inputs (categories) come from a minority of the results (frequencies)

• The majority of the frequencies come from a majority of the inputs (categories)

• The majority of the inputs (categories) come from a majority of the outputs (frequencies)

What does a pie chart represent?

• Categories of data in relation to the whole

• The total frequency of quantitative data

• Proportion or percentage of observations

• Differences between groups of data

What types of data should be use when creating a bar plot or a pie chart?

• Qualitative data

• Quantitative data

• Both qualitative and quantitative data

• Discrete and continuous

What should be the focus based on the Pareto chart of customer complaints in the video?

• Delayed delivery and pizza not hot

• Inadequate topping quantity and pizza too hot

• Early delivery and inadequate topping quantity

• Delayed delivery and poor customer service

What is the purpose of organizing and summarizing data?

• To make the data more manageable and provide insights

• To make the data more readable and colorful

• To make the data more complex and confusing

• To make the data more detailed and specific
