What are the three different ways to break down the percentages in a contingency table?

Choose the correct choice below.

A.

The percentages in a contingency table can be broken down into a percentage of the overall total, a percentage of the rowtotal, or a percentage of the column total.

B.

The percentages in a contingency table can be broken down into a percentage of the variable total, a percentage of the rowtotal, or a percentage of the column total.

C.

The percentages in a contingency table can be broken down into a percentage of the overall total, a percentage of the variable total, or a percentage of the cell total.

D.

The percentages in a contingency table can be broken down into a percentage of the cell total, a percentage of the rowtotal, or a percentage of the column total.

What type of insights can you gain from a contingency table that contains three variables that you cannot gain from a contingency table that contains two variables?

Choose the correct choice below.

A.

A contingency table that contains three variables can reveal additional patterns that cannot be seen in the two variable contingency table. However, one cannot change the statistic displayed and compute descriptive statistics.

B.

A contingency table that contains three variables can have more than three percentage breakdowns while a contingency table that only contains two can only have three percentage breakdowns.

C.

You cannot gain any additional insights from a contingency table that contains three variables that you cannot gain from a contingency table that contains two variables.

D.

A contingency table that contains three variables can reveal additional patterns that cannot be seen in the two variable contingency table. One can also change the statistic displayed and compute descriptive statistics which can add insight into the data.

What is the difference between a time-series plot and sparklines?

Choose the correct choice below.

A.

A time-series plot is a type of scatter diagram with time on the y-axis. Sparklines are a compact time-series visualization that can reveal patterns that the time-series plot may not.

B.

A time-series plot is a type of scatter diagram with time on the y-axis. Sparklines are an expanded time-series visualization that can reveal patterns that the time-series plot may not.

C.

Sparklines are a type of scatter diagram with time on the x-axis. A time-series plot is a compact sparklines visualization that can reveal patterns that the sparklines plot may not.

D.

A time-series plot is a type of scatter diagram with time on the x-axis. Sparklines are a compact time-series visualization that can reveal patterns that the time-series plot may not.

E.

A time-series plot is a type of scatter diagram with time on the x-axis. Sparklines are an expanded time-series visualization that can reveal patterns that the time-series plot may not.

F.

Sparklines are a type of scatter diagram with time on the y-axis. A time-series plot is a compact sparklines visualization that can reveal patterns that the Sparklines plot may not.

What are the advantages and disadvantages of using a bar chart, a pie chart, a doughnut chart, and a Pareto chart?

What are the advantages of using a bar chart, a pie chart, a doughnut chart, and a Pareto chart? Choose the correct choice below.
