u-Chart
Give this one a try later!
Used to chart the number of defects per unit when the
subgroup size is variable or constant. This chart assumes
that the process has a Poisson distribution.
The Empirical Rule
Give this one a try later!
The rules gives the approximate % of observations w/in 1
standard deviation (68%), 2 standard deviations (95%) and 3
, standard deviations (99.7%) of the mean when the
histogram is well approx. by a normal curve
Descriptive statistics
Give this one a try later!
numerical data used to measure and describe
characteristics of groups. Includes measures of central
tendency and measures of variation. Graphs such as pie, bar
and line graphs, histograms, boxplots, scatterplots, etc. and
numerical summaries like means, variances, etc. are
examples
bar chart (relative frequency bar chart)
Give this one a try later!
A chart that represents the count (or percentage) of each
category in a categorical variable as a bar, allowing easy
visual comparisons across categories.
Cpk
Give this one a try later!
a measure of the actual process capability. It is calculated by dividing the
distance of the process mean to the nearest tolerance limit by 3 standard
, deviations of the process.
A measurement system can be characterized, or described by: Location (Average
Measurement Value vs. Actual Value):

Stability, Bias (Accuracy), and Linearity are the three tools that make up this
measurement system category
Bias (Accuracy)
Give this one a try later!
a measure of the distance between the average value of the measurements
and the "True" or "Actual" value of the sample or part.
Cpk and PpK difference

Cpk is what you could be doing and Ppk is what you are doing.
