Statistics is nothing more than the study of data. A statistician acquires data, organizes it, and analyzes the results. They do so in order to make sense of the data that has been collected to ensure it serves as more than information overload. The results are then applied to other areas of study. Cazoom Maths offers enjoyable and easy statistics worksheets as resources for students and teachers.

Among the applications of statistics is when a statistician collects information. A sample of the population is used. The individual typically cannot survey everyone in a group or study them because the numbers are simply too big. The sample is nothing more than a portion of the population that is believed to be representative of the entire group.

To determine the average weight of adult Americans, the statistician would survey a few thousand adults. If the sample accurately reflects the population, the average height determined by the results would be very close to the average height of adult Americans as a whole group.

How does a person go about collecting these stats? Examples of statistics can include a variety of methods. The method selected depends on the question being asked by the statistician and the statistical information to be collected. Simple random samples are one option, but a person might find he or she benefits more from a cluster or stratified sample.

Regardless of which method is selected, the statistician must share this information with others so they can replicate the study if desired. Each type of sample has its benefits and drawbacks, which need to be considered before the data collection process begins.

As data is collected, it must be organized to ensure information can be pulled from it. A statistics worksheet offered by Cazoom Maths can help students learn how to gather and organize the data. With these worksheets, students can spot trends and patterns.

When comparing stats worksheets, students must decide if they will benefit most from a worksheet with a pie chart, one that creates a circle graph, or if another option should be selected. Other choices include stem-and-leaf plots, scatterplots, bar graphs, box-and-whisker graphs, and time plots.

When using descriptive statistics, researchers look to calculate quantities that accurately describe the data collected. The mean, median and mode provide information about the center or average of the data, while the standard deviation and range provide information about the data spread. Other techniques include regression and correlation and are used to provide information about paired data.

Hypothesis testing is a major part of inferential statistics. Researchers start with a sample and use the material gathered to try to infer something about the overall population. A hypothesis is formed before researchers use statistical tools to decide whether to accept or reject the theory.

Statistics are important because almost every scientific research field uses statistics in one way or another. Advertising is a good example, while psychologists use statistics to learn more about a patient with relation to the general population. Economics is another field that relies on statistics and the same is true of medicine along with many other areas.

Statistics is a difficult subject for many students. They struggle to determine the probability of an event or whether an occurrence is random. Fortunately, with the help of statistics worksheets offered by Cazoom Maths, the entire process becomes clearer.

Be aware that, as Mark Twain pointed out, the person using the data determines in part how it is shared because statistics are pliable. For this reason, worksheets are of great help. They can teach a student to see trends and patterns before any analysis is conducted.
