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.
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.
Do you need to know not only what the standard deviation, the spread and the range of a sequence of numbers are but also how to calculate them? If so then this App is for you. Not only will this App tell you the answer but it will also tell you how you can work it out for yourself using the information you have provided. Great for helping children trying to understand these concepts and for reminding yourself about them.
Just select the field at the top of the screen and a keypad will be shown. You type in the numbers in the sequence separating them using the space key (the empty key at the bottom left). When you have added all the numbers press the OK button. The keypad disappears and the answers are presented below in the table. On the iPhone there is another button at the top that leads to a page that explains how each of the averages was calculated. On the iPad the table to the right has the explanations.
The App calculates the Range, the lower quartile value, the upper quartile value, the interquartile range, and the standard deviation. It also explains how to calculate each of these values and in the case of the standard deviation shows you to different methods for calculating it.
** Non-ad version available for purchase ($0.99) **
The normal curve is used in many statistical calculations. BellCurve is an easy to use calculator that finds probabilities in a normal distribution.
BellCurve consists on two views. The main view displays the normal curve, with probability of interest shaded in. Lower and upper bounds can be changed using the slider. The flipside view allows users to specify exactly the expected value (mu), the standard deviation (sigma), the lower bound (green dot) and the upper bound (red dot). Z scores are also shown.
