Housing price scatter diagram slide 51: Height tools Age Fig 3 : Height.
Method OF USE Used for tallying the occurrences of the defects or causes being addressed and graphing or charting them directly.11, example Bar Graph Line Graph 95 5 Radar Graph Pie Graph 12, check Sheet Check sheets are sheets that are design in advance to tools collect the necessary data easily and systematically, which allow the efficient checking of all items for inspection and verification.Determine the largest (L) and smallest (S) value of data.Sealing temperature Model A Model B scatter diagram slide 52:.Dram tools the middle bones, small bones and fine bones.WHY-WHY analysis slide 53: WHY-WHY analysis WHY-WHY analysis It requires asking cause till we reach the systems cause of the problem.It is a good communication tool that describes the data in a simple and easy-to- read bar diagram.Check tools Ensuring the effectiveness of remedies.These are the tools which facilitate the organization to resolve the basic problems.As a result we get a diagram with branches tools and sub branches of causal factors resembling to a fish bone diagram.The measures commonly used to describe central tools tendency are:.Slide 48: scatter diagram scatter diagram: Prepared by plotting paired sets of data against each other on x and y axes. Specify the allplayer aim of collecting data.
The graph helps check for outliers too.
