Every basic thing we use in life consist of history. That means statistics. Taking into account the past and the future, and keeping record of what has been done. Without statistics we won't know what worked and what didn't. It helps us to find balance and structure.
Companies make thousands of products every day and each company must make sure that a good quality item is sold. But a company can't test each and every item that they ship to you, the consumer. So the company uses statistics to test just a few, called a sample, of what they make. If the sample passes quality tests, then the company assumes that all the items made in the group, called a batch, are good.
I pulled out the statistics from that article and from the England and Wales Crime Survey (Home Office data) and displayed them in the picture above (click to enlarge). I chose to use only the four most commonly used drugs for the graphic – cannabis, cocaine, ecstasy (MDMA) and ketamine (discounting laughing gas for which only the student data was available -45 % had tried it!). For those four drugs shown the student population was at least twice as likely to have tried a drug (cannabis) up to ten times more likely (ketamine) than the general population.
Rationale: Adult education should put less emphasis on teaching isolated mathematical skills and increase emphasis on teaching the math of life skills and the world of work. Investigation of statistics and probability should actively engage learners in exploring events and making predictions about situations relevant to their daily lives. Adults know that decisions made on the basis of various statistics affect them daily. Collection, organization, calculation, and interpretation of data are fundamental to our personal lives and the lives of most adults in the workplace. Adults use and analyze statistics and, formally or informally, predict outcomes daily.
Data should be collected for at least a month to allow for patterns to form. Make smaller outline maps and have students use different techniques to illustrate the pattern of crime. Discuss who is interested in such statistics. Invite a police officer to close this activity by bringing in statistics for a longer period of time to see how their short sampling compares.

This chapter taught me the importance of understanding statistical data and how to evaluate it with common sense.
Therefore, it is important that adult learners understand how statistical representations and calculations are used. There isnothing more indigenous or relevant to human life than mortality. Using mortality tables from different time periods is an effective way to investigate changes and predict future change. It also is a means of getting adults who smoke (many of our students do) or have other dangerous lifestyles to consider their own mortality
Join us as we explore how math can help us in our daily lives. In this exhibit, you'll look at the language of numbers through common situations, such as playing games or cooking. Put your decision-making skills to the test by deciding whether buying or leasing a new car is right for you, and predict how much money you can save for your retirement by using an interest calculator.
Since chemicals have become so ingrained in our daily lives, it would be a challenge to eradicate them completely. Keeping your exposure to a minimum is the best you can do to protect your home from the harmful effects of these chemicals.
Statistical knowledge is important in problem solving and decision making. Adults, often without realizing it, make decisions, based on statistical information. It may be via the television, radio, or it may be through print materials. Statistical information is used to communicate information and sometimes influence others. Understanding the flood of statistical information allows adults to make more informed decisions.
One of the largest businesses in the United States which relies heavily on statistics and probability is insurance. It is very important to an insurance company to know how to measure the risks against which people are buying the insurance. In order to set the premiums, a fire insurance company must have some way of knowing how many fires will occur. An automobile insurance company must be able to predict the number of accidents involving injury, loss of life, and property damage. A life insurance company must know what the expected number of deaths will be in a given group of policyholders.
There is also the need to have the ability to read and interpret statistical process control charts. Employers want everyone to understand quality. Any chart or graph that shows production uses statistics. Other forms of charting are also used in the workplace to make decisions as well as gauge accuracy.
Data collection, analysis, and graphing are essential in the workplace. Many industries, manufacturing in particular, now use statistical control processes to monitor their processes in order to ensure quality products. Often the front line employee is required to collect the data used for charting the manufacturing process; therefore, employees at all levels should be knowledgeable about and comfortable with using a variety of charts. As more and more quality teams, consisting of a variety of employees, are charged with the task of ensuring quality products, employees will need to have an understanding of probability and sampling.
