Chapter 1: Introduction
The “Control Charts Generator in Android” is an Android platform based application which provides the mobile phone user to generate various control charts like X-Bar Chart, R Chart etc. using their smartphones at any place, any time, free of cost and without internet connection.
In a nutshell, this application helps a common smartphone user with no major background in statistics and no access to costly mathematical software to generate control charts anywhere anytime and save results in .png format, pdf format.

1.2. Existing System
There are two ways to generate control charts:
1. Manually: We perform the calculations using a calculator or by hand and generate control charts on a graph sheet.
2. Using Software: We use software available in market.
1.3. Problems in Existing System
There are many limitations in the existing system be it manual or software.
Problems in Manual by Hand Approach:
1. Time Consuming: Drawing charts by hand is time consuming as it involves a lot of calculations.
2. Error Prone: The calculations made by hand or using calculations are prone to error.
3. Inaccurate Charts: The charts generated by hand on paper sheets are irregular in shape and inaccurate.
4. Difficulty in Maintaining Record: The charts drawn on paper are difficult to store and retrieve at later time for comparisons.
Problems in Software Approach:
1. Cost of Licensing: There are many
* Charts and Pictograms - Charts and pictures can present observation data in colourful ways to make your portfolio appear more interesting.
b) (10 points) Based on your results in a), graph publishers on a bubble chart using the
Figure 1. Average Time Spent on Each Writing Utensil per 60 Seconds. Error bars represent one standard deviation above and below the mean.
After each procedure, a graph was created for each set of data to compare and contrast results.
A process that monitors standards by take measurements and corrective action as needed. It is in control when only variation is natural, if variation is assignable then discover cause eliminate it. Take samples to inspect/ measure- reduce inspection time, reduce opportunity of bad quality. Control charts graph of process data over time-show natural and assignable causes. Control charts for variable data (characteristic that is measured, length,height, etc) are X-chart (average) and R-chart (range)must use x and r to get correct results. central limit theorem follow normal curve. When we know . When we don’t know . Control charts for attributes (categorical-defective, good/bad) P-chart (percent) or C-chart
One of the most common technology used for outlining subconsciously using graphs, bar charts, especially the one that shows all the information in the order, or bar charts, histograms, which is among a wider group.
Other skills introduced in this book includes using tally marks to collect the data for your charts, using number lines to introduce negative and positive numbers, and using that number line to solve problems.
· Incorporate at least one image and at least one chart or graph illustrating project
Based on this sample and the control chart limits that you calculated in part (a), is the process in control? Why or why not?
Go by the worksheet to fill in all needed data then review the data with the subject before they leave. This will cut down on misremembering information. In regards to mis-recording data get someone to review your information or review it yourself the next day. When writing down lab values I can record it and then get someone to call out the lab values while I double check them. Our after getting rest I can look at the information with fresh eyes and double check myself. I believe that this is a major error. One number being off can skew the results drastically. By improving upon this error, I believe statistical information will be better.
In each meeting the data of every area is presented to the board in many ways. One of the most popular and useful are infographics. Some of them are hanged around the school so parents, teachers and students can see them.
Q7: Create a bar graph or pie chart of the data you have collected. For example, you could create a bar graph that shows the employee turnover rate in organizations that do offer flexible work arrangement compared to organizations that do not. Alternately, you could create a pie chart that shows which types of flexible work arrangement workers want the most.

The scatterplot is another useful tool when I need to present visual data. I believe that this would be helpful in presenting the age of materials that a school or department has in their inventory. With the scatterplot tool we could have the number of copies on one axis and the copyright year on the other axis in order to not only show the age of their inventory, but also how many copies you have available for each copyright. This information is helpful when departments or schools are looking to weed materials, but may not know where to start. Presenting such data would be the first step and the second would be then to determine circulation of the older copyrighted materials and use the two reports to determine whether to keep or get rid of the title. Sometimes not looking at the title of a book, which may be one of your favorites or one you are not fond of, can be helpful because you are reducing your biased opinion of the materials that may not be circulating. Of course there is more to it than this, but this would give them a good starting
It is a simple form of check sheet used to collect measured or counted data in a tabular form. Data is collected by making tick marks. It can be broken down to show shift, day or month. One precaution to be taken is to leave enough room to write individual measurements.
