Description
Statistical Process Control is a statistical tool of Statistical Quality Control, used by the quality professional. Control Charts aid the Six Sigma professional in the process of determining if a process is under control.
All you need to do is to enter numbers separated by spaces and see the results immediately.
List of features:
 XBar Chart
 Range (R) Chart
 PChart
 CChart
 Process Capability, Cp, Cpk
 Theory and examples.
Statistical Process Control is applied in order to monitor and control a process. SPC can be applied to any process where the "conforming product" (product meeting specifications) output can be measured. Applied to Production processes as well as services, Hotels, Restaurants, Banks...
You could study the examples and try to design a method to monitor your production process or service.
Your last data are persistent. You can close and reopen your app and to continue adding data. data will be deleted when you start a new data set.
Your comments will be appreciated and I have the commitment of improve the application with more features.
You must install this app before submitting a review.

Statistics 1
$0.99 for a limited time!
Coming Soon to the Android version  Quizzes & Calculators
Intro Statistics ETextbook with: lessons, flashcards, decision trees, a glossary, and a list of formulas and symbols.
It's the perfect tool for students in an intro statistics course, or professionals who need a Stats 101 book on their phone.
Statistics 1 was pilot tested in a statistics course at Abilene Christian University. Here’s what some of the students had to say:
“It gives reallife examples in each lesson and tables so I can easily reinforce the information I just read.”
“It's a great tool to go to for an easy answer. Instead of searching through a whole textbook I can click on a specific section in the app and find the answer easily and see a graph that represents the idea.”
Coming soon: Quizzes, calculators, and sims.
The app was designed by educational psychology Ph.D.s, statistics teachers, and software experts. Many of us learned stats the traditional, boring way – through books and lectures. We always wanted more interactive, visual, and engaging ways to learn stats. Stats has many abstract concepts so we use realworld examples to anchor your understanding.
 "Cliff Notes  Statistics" book or pdf sells for $16.99.
 "Statistics for Dummies" sells for $19.99.
 "The Complete Idiot's Guide to Statistics" sells for $18.95

courses, or if you just need these tables!
For both Phone and 10' tablets.
These tables give you the probabilities
associated with your test statistics and
parameters.
To use these tables, just select the
distribution you want, and put in the
test statistic and parameters, and the
APP tells you the related probability.
*************************************
1) For the Normal Distribution:
Enter your Z Score, and you get
the left, right tails and the range.
2) For the Binomial Distribution:
Enter n  number of trials,
p  probability of success,
x  number of successes
and you get the probability of
x, or the cumulative probability
for x.
3) For the Poisson Distribution:
Enter the mean, and number of
occurences, and you will get
the Probability of the number
of occurences, and the cumulative
probability.
4) For the t Distribution:
Enter t and the Degrees of Freedom
and you will get the probability
of the left and right tails, and
the two tailed probability.
5) For the f Distribution:
Enter the f statistic, and the
Degrees of Freedom for the numerator
and denominator. You will get the
probability for the right tail
(alpha for the ANOVA test).
6) For the ChiSquare Distribution:
Enter ChiSquare and the Degrees of Freedom
and you will get the probability
of the right tail.
7) Inverse Normal.
Enter the probability of the
Normal Distribution left tail,
and you get the Z statistic.
8) Inverse t
Enter the probability of the
t distribution left tail, along with
the degrees of freedom, and you will
get the t statistic.
Confidence Intervals:
Sigma Known. Uses the standard
CI formula (Using Z) to determine the range with
CI% chance of containing the true mean
of the population.
Sigma unKnown. Uses the standard
CI formula (Using t) to determine the range with
CI% chance of containing the true mean
of the population.
CI for a proportion. Uses the standard
CI formula (Using p,n,Z) to determine the range with
CI% chance of containing the true mean
of the population.
