# Seven Basic Quality Tools

SKU: C-991Duration: 11 Minutes

The seven basic quality control tools are a set of commonly used graphical statistical analysis tools. They can be used to help solve many different types of problems, not just quality problems. The seven tools are: cause and effect diagrams, check sheets, control charts, histograms, Pareto charts, scatter plots, and data stratification. It is important to understand the purpose of each of these tools and how to interpret the information. This 7 QC tools training course provides a summary of each tool, including common uses.

### Key Questions

The following key questions are answered in this module:

What is a check sheet used for?
Check sheets are simple data collection tools. They have many purposes, including collecting data on the frequency or location of problems.

What is a histogram?
A histogram is a special bar graph that is used to show how often a value, or range of values, occurs in a given time period. Using a histogram, you can tell if data is normally distributed, the process is capable of meeting customer requirements, changes have occurred in the process, or how two processes compare.

What is a Pareto chart?
A Pareto chart is another special kind of bar chart that shows the relative frequency or magnitude of a problem or cause. The bars are arranged in order from longest to shortest to identify the most frequent problem.

What is a scatter plot?
A scatter plot is a graph of paired numerical data that is used to understand the relationship between two variables.

What are the 6 Ms?
For production processes, most possible causes will fall into one of six categories: Machines, Methods, Materials, Measurements, Mother Nature, and Manpower. These six categories can be used to help identify possible causes on a fishbone diagram.

The seven basic quality tools are a set of commonly used graphical statistical analysis tools. They can be used to help solve many different types of problems, not just quality problems. The seven tools are: • Cause and effect, or fishbone, diagrams • Check sheets • Control charts • Histograms • Pareto charts • Scatter plots • Data stratification (classification) Most of the time you will end up using a combination of these tools. Each tool will now be described in more detail.
