1, Statistics Practice Problems For Dummies Cheat Sheet - dummies


By Consumer Dummies. Statistics problems take on a wide range, from pie charts, bar graphs, means, and standard deviation to correlation, regression, confidence intervals, and hypothesis tests. To be successful, you need to be able to make connections between statistical ideas and statistical formulas. Through practice, you see what type of technique is required for a problem and why, how to solve statistics math problems, as well as how to set up the how to solve statistics math problems, work it out, and make proper conclusions.

Most statistics problems you encounter likely involve terminology, symbols, and formulas. No worries! This Cheat Sheet gives you tips for success. Like every subject, statistics has its own language. The language is what helps you know what a problem is asking for, what results are needed, and how to describe and evaluate the results in a statistically correct manner.

Four big terms in statistics are population, sample, parameter, and statistic:. A population is the entire group of individuals you want to study, and a sample is a subset of that group. A statistic is a quantitative characteristic of a sample that often helps estimate or test the population parameter such as a sample mean or proportion.

Descriptive statistics are single results you get when you analyze a set of data — for example, the sample mean, median, standard deviation, correlation, regression line, margin of error, and test statistic. Statistical inference refers to using your data and its descriptive statistics to make conclusions about the population. Major types of inference include regression, confidence intervals, and hypothesis tests.

Here are some helpful tips:. Formulas for descriptive statistics basically take the values in the data set and apply arithmetic operations.

Often, the formulas look worse than the process itself. The key: If you can explain to your friend how to calculate a standard deviation, for example, the formula is more of an afterthought. Formulas for the regression line have a basis in algebra. The y- intercept, a, is where the regression line crosses the y- axis. All the various confidence interval formulas, when made into a list, can look like a hodge-podge of notation. However, they all have the same structure: a descriptive statistic from your sample plus or minus a margin of error.

Hypothesis tests also have a common structure, how to solve statistics math problems. Although each one involves a how to solve statistics math problems of steps to carry out, they all boil down to one thing: the test statistic. A test statistic measures how far your data is from what the population supposedly looks like. It takes the difference between your sample statistic and the claimed population parameter and standardizes it so you can look it up on a common table and make a decision.

Symbols or notation found in statistics problems fall into three categories: math symbols, symbols referring to a population, and symbols referring to a sample.

Math symbols are easy enough to decipher with a simple review of algebra; they involve items such as square root signs, equations of a line, and combinations of math operations. The other two categories are a bit more challenging, and knowing the difference between them is critical.

Solving statistics problems is always about having a strategy. Hint: Questions typically tell you what they want in the last line of the problem. Cheat Sheet.
