Question

Too many observations on one side of the center line on a run chart is an indication of what?

A) trend
B) too much dispersion
C) cycles
D) bias
E) level shift

Answer 1

In answer to the student's question, too many observations on one side of the center line on a run chart indicate a 'level shift,' which is a sudden change in the data level.

Step-by-step explanation:

When a run chart reflects too many observations on one side of the center line, it is an indication of a non-random pattern. These patterns can denote various changes or shifts in the data being analyzed. The correct answer to the student's question is E) level shift. A level shift refers to a sudden change in the data level, contrasting with normal fluctuations or random noise within the data. This could be a result of a process change, or an external factor affecting the measurements.
