XbarRChart

XbarRChart

APPSKOUSIKA SOTWARE DEVELOPERS (OPC) PRIVATE LIMITED

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.

UnpairedT

UnpairedT

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.

A/B Test Calculator

A/B Test Calculator

Mikihiro Fujiwara

"A/B Test Calculator" tell you what percentage are statistically significant of your A/B test results.



The A/B test, it is mainly carried out in the Internet marketing, generic name of the test for the policy decision.

++ The A/B test in the web site ++
The A/B testing of web sites, by altering a portion of the web site, consider which of the parts "A" and "B" in the web sites in comparison is superior in terms of usability.

++ The A/B test in Internet advertising ++
In the A/B test in Internet advertising, by separating out the creative evenly, it compares either of ad you want to compare "A" and "B" raises more achievements, to determine the adopted advertising.

++ The A/B test in landing page optimization ++
A/B testing of landing page optimization, the landing destination page of Internet advertising is more prepared, by distributing the landing destination, and compares whether the landing page "A" and "B" is increased more outcomes employed It will determine the landing page to be.



The following is a quote from "The A/B Test: Inside the Technology That’s Changing the Rules of Business" (http://www.wired.com/2012/04/ff_abtesting/).

The testable web is so much safer. No choices are hard, and no introspection is necessary. Why is B better than A? Who can say? At the end of the workday, we can only shrug: We went with B. We don’t know why. It just works.

Quick Confidence Interval

Quick Confidence Interval

MSYapps

In statistics, confidence intervals can be used to express the degree to which sample results are reliable.

Confidence intervals are often stated in terms of a percentage like 90% or 95%. When the sample or population distribution is the Normal (bell-shaped) distribution, the confidence intervals can be represented as a number of standard deviations (σ) above or below the sample mean (μ).

Moving the slider beneath the graph will vary the confidence intervals from 50% to 99%. Additionally, you may choose the two-tailed confidence intervals or the one-tailed interval by tapping the button beneath the slider.

In this application, you may chose the standardized Normal distribution with μ=0.0 and σ=1.0 or some other values for mean and standard deviation.
