Xbar and R chart are used to check whether the given process is under Control.These charts are used as tools of SPC(Statistical Process Control).

Each subgroup need to have two or more measurements/readings but less than or equal to nine measurements.Two or more subgroups but preferably less than or equal to twenty subgroups are needed.

First, name the Process and enter number of measurements per subgroup(n),and enter number of subgroups(k).

Then enter measurements/readings separated by comma(,) and enter subgroups separated by semicolon(;).

Example 2.01,2;2.01,2.01;2.013,2.01;2.0,1.99;1.99,2.01;2.01,2.0;2,1.99;1.98,2.0;2,1.99;2.01,2;2.01,2.01;2.013,2.01;2.0,1.99;1.99,2.01;2.01,2.0;2,1.99;1.98,2.0;2,1.99;2.0,1.99;1.99,2.01

As a first step make R Chart.If you find the R chart to be valid (within limits),close the chart and make x bar chart.The following points on x bar chart indicates out of control(SPC) process:

a. one point outside the 3 sigma control limits

b. eight successive points on the same side of the centerline

c. six successive points that increase or decrease

d. two out of three points that are on the same side of the centerline,

both at a distance exceeding 2 sigma’s from the centerline

e. four out of five points that are on the same side of the centerline,

four at a distance exceeding 1 sigma from the centerline

As you make the R chart the details are saved.You can open Sample group List(Menu > sample group list) to find the saved details and charts.You can share the charts(print/email).Menu > New Sample Group enables you to make new charts.

Yasunari Miyagi, MD

A tool of statistics for scientists, doctors, researchers, students, etc.

This App handles unpaired t-test and Welch's t-test, that are automatically selected by variance comparison test. The confidence intervals of the difference of two averages are also provided.

This is a useful test for the comparison of mean for two independent groups.

At first, the variance (=standard deviation^2 = SD^2) of the data are tested. If the variance of the groups are not different, t-test (Student t-test) is applied automatically. If different, Welch's t-test is applied. When P value is less than 0.05, the averages of two groups are different. When P value is equal or more than 0.05, the averages are not different. If you like to know the confidence intervals of the mean difference, adjust the control bar. By default, variance criteria = 0.1, confidence interval=0.95. The total number of elements should not be over 500.

Bootstrapping is a technique for measuring sample statistics from a relatively small set of data elements. By randomly resampling with replacement from the array of data elements, the software is able to generate a distribution that approximates the Normal Distribution from which parametric statistics like mean, standard deviation, skewness, and kurtosis can be estimated.

In this application, there must be at least 6 data points (0 is a number) and resampling will create 10,000 or more sets, each of whose size will be user-defined in the iPad version or 2 in the iPhone version.

The iPad version allows for more resampling latitude and enhanced data entry. Another feature is the ability to add, retrieve, reorder, or delete data sets.

Results from the iPad version may be shared via email, text message, or print.
