3D surface plot
What is a Histogram?
What is a Dot plot?

1. Upward or downward trends
2. Changes in the amount of variation
3. Differences between long term and short term

What is a Run Chart?
What is Data Stratification?
Why use Data Stratification?
The root causes of the worst performing subgroups can be investigated by using 5Whys and Fishbone Diagram etc.
What are Multi-Vari Charts?
What is a Box Plot?
Box plot compiles of the ''box'' and the ''whiskers'' on each side of the Box.
A Box exists from 50% of the data and start at Q1 and ends at Q3, the middle line in the box is the Median, not the average.
The whiskers represent the range of the data (minimum to maximum)
What are Individual Value Plots?
Used as a visual display of data.
What are 100% stacked bar charts?
Pareto is great for one sample, 100% Stacked bar chart is great for comparing 2 or more samples.
Since the sample size is not readable in this chart it is considered wise to note the sample size near the graph.
What is a Scatter Plot?
When a relationship exists the data points will show a clear trend or pattern when no relation is there, the data points will be random.
What is a Bubble Plot?
What is a Matrix Plot?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
