Procedure for the application of statistical techniques

The purpose of this procedure, with the goal of building a statistic to measure processes and customer satisfaction, as the section identifying the needs of continuous improvement, has been established. At the same time, regulate the use of methods of the Pareto diagram to show all the contributions to the overall result in order of importance.

1 Principles for the application of statistical methods

o Choose the units of measurement for determiningTime, cost and / or give to other units of the rate impact.
Drawing objects or from left to right on the horizontal axis (x axis) in ascending order of values, can be combined in the object "other." The item will be placed to the right.
Draw 2, or vertical axis, a beginning and an end to the horizontal axis. The size of the unit that remains is identified by its height equal to the sum of all objects. The right one is thesame height and size is divided by 0% to 100%.
o In each object, draw a rectangle whose height is the height of the units represents the object.
o Set the cumulative frequency line with the addition of all amounts of objects from left to right.
o Use Pareto to identify the important objects in order to improve its quality.
Comparison or improve the table before and after to determine the effectiveness of the estimateImprovement.

2 Production and price statistics

Collect all the departments or to report the daily progress of the department of production planning.
o Production of these factors should include: date, style, product names, color, size, the daily amount of money progressive journalist.
o The planning department there are a total relationship of the workshop, including the date, style, product name, the number of contracts, the amount of cutting andSewing, the amount of finished products, the amount of raw materials, the unit price of each style and the great value of each style.

3 Weaknesses and improve the statistics

Every day or product quality inspection department to collect the amount of defects in any work of any kind, the ratio of big mistake for any product, technical and production department to be entrusted to them for repair.
o At the end of eachProduction order, collects the product quality inspection department and do statistics on all defects Pareto chart / columns to find the solution for subsequent production orders.

4 Customer feedback and statistics

voice of the customer or are being collected in a separate file folder.
o If all opinions were gathered, is to establish the commercial office and analyze the Pareto diagram.

Politics as usual – Lying with statistics

Lying with statistics has always been part of politics, but perhaps become more common as we become mathematically literate as a people. In fact, 65.7% of statistics are simply wrong. Okay, I invented that one – but to make a point. One of the easiest ways to lie with statistics is to make them. How "accurate" makes it believable, so I do not want that around 67% discount.

Make unrealistic exact number when reading orStatistics here. Nobody can really say to the nearest hundredth of a percent, as the population is overweight, for example, or those who are homeless. But what to look for?

Here's an example taken from a magazine I read. The May 2008 issue of Sierra Magazine had a small piece on the "hyper-sheet, carbon-spewing ways" of Western countries, with the following quote: "Stephen Pacala, director of the Princeton Environmental Institute,argues that the world's richest 700 million people – only 7% of the world – are responsible for half of global emissions of greenhouse gases from fossil fuels "Notice created when 700 million were up 7% of world population, we suddenly have 10 billion people. worldwide. The actual number was about 6.7 billion 2008th

This type of error is common in the report. It 's very likely a simple mistake, but on the other hand, it appears that the figures are often wrongbest for the production of the desired position as the true dignity. It's bad enough when only 10.3% of the world to produce more than half of the carbon dioxide emissions, but are also the most politically strong point, if only 7%. Look for this type of errors and / or manipulation of statistics.

Another example of lying with statistics, see the election coverage. More than once I have given the percentage of votes for Republican candidates and Democrats saw a 100% in key elections – evenPresidential elections. Certainly true being, would not vote for other candidates. In fact, other parties often several percent of the vote. As for the news organizations are referring to is apparently the items that they think matter. This type of manipulation gives the impression that there are other political parties, but there were a dozen presidential candidates who voted for the last time I raced.

Attention, even the most subtle horizontalStatistics. For example, I ask you a question: If a company profits to go from 3% to 6%, increased by 3% or 100%? The profits have doubled, an increase of 100%, but as a return on equity, they moved just 3% to 6% that still leaves a bad return compared to most sectors.

As this report is based on the political inclination of the head. If you want to attack the company for too much money, they may have to write a headline that says: "Company XYZ sees 100%Increase Profits! "Technically it is an accurate statement, but hides a lot of truth, right?

Lying with statistics is perhaps most evident in the polls. In this case, the manipulation of truth by the way in which issues are made. If a thousand people were asked: "If the government helps people at risk of losing their homes to foreclosure," the number of people for such a program would certainly be higher if a thousand were asked: "Should weforced to pay more taxes to help people who have paid for their homes? "Note that both describe exactly what the program would do.

As you do, watch the evening news or read newspapers and magazines, provides support in every statistic is thrown away. Ask if it is more accurate, probably, and as he came. Ask if they tell the whole truth, and what could be measured in other ways things. Get online and search for more information. Continue to lie with statistics, butbe deceived by them is optional.

Important information on motorcycle helmet laws

Motorcycle racing is much more difficult than driving a car. A statistical report issued by the Government shows that the number of deaths from accidents, bicycle accidents have been nearly thirty seven times larger than that of deaths by car. However, there are some states that do not have to wear a rule for the driver with a helmet while riding a bike. has a study by the Federal Office of Road Safety, reported that the majority of motorcycle accidents end in deathbecause of not wearing a helmet.

In fact, three of the five motorcycle accidents result in head injuries to riders not wearing a helmet. But it is very important to note that if you were searching for consultation with a face motorcycle accident, do not forget a lawyer about your legal rights.

There are some states that have a legal minor, when, if you are under a certain age, you must wear a motorcycle helmet. This is a good law for children who are riding with theirThe parents, but what their parents? Since many countries have no laws or rules requiring that adults must wear a helmet States. In reality, this law is useless, because most children follow their parents in all aspects, so that when their parents are not wearing a helmet while driving, then your child like to feel that there is no need for them a lot. The bad news is that the parent who owns a motorcycle, this could also be supported.

This law is particularlyState to state, but some do not even have a law to wear a helmet while riding motorcycles, like New Hampshire, Iowa and Illinois. In some other states, use the 'e' law, where the use of a helmet is for people who require between 17 and 20 years. This is because these states that people can not under the age of twenty years, the necessary skills, a ride, so wearing a helmet is required. They believe that an adult has sufficient maturity and capacity,Do not use the bike without a dangerous situation.

In some states like Alabama, California, Georgia, Missouri and Oregon, there is a law, who was not wearing a helmet while driving, as it is, to take the person riding the bike must wear a helmet. In California, after spending the mandatory helmet law, motorcycle deaths fell Thirty-seven per cent.
