How to Calculate and Interpret a Correlation (Pearson's r)

Any time data are collected and analyzed, statistics are being done. This can range from government agencies to academic research to analyzing investments. Economists collect and look at all sorts of data, ranging from consumer spending to housing starts to inflation to GDP growth. In finance, analysts and investors collect data about companies, industries, sentiment, and market data on price and volume. Together, the use of inferential statistics in these fields is known as econometrics.

Key Takeaways Statistics is the study and manipulation of data, including ways to gather, review, analyze, and draw conclusions from data. The two major areas of statistics are descriptive and inferential statistics. Statistics can be used to make better-informed business and investing decisions.

Related Terms Descriptive Statistics Definition Descriptive statistics is a set of brief descriptive coefficients that summarize a given data set representative of an entire or sample population. Sample Size Neglect is a cognitive bias whereby people reach false conclusions by failing to consider the sample size in question. Nonparametric Method Nonparametric method refers to a type of statistic that does not require that the data being analyzed meet certain assumptions or parameters.

T-Test Definition A t-test is a type of inferential statistic used to determine if there is a significant difference between the means of two groups, which may be related in certain features. Partner Links. Ratio data — data is continuous, ordered, has standardized differences between values, and a natural zero. Once you have identified your levels of measurement, you can begin using some of the quantitative data analysis procedures outlined below. Due to sample size restrictions, the types of quantitative methods at your disposal are limited.

However, there are several procedures you can use to determine what narrative your data is telling. Below you will learn how about:. The first thing you should do with your data is tabulate your results for the different variables in your data set. This process will give you a comprehensive picture of what your data looks like and assist you in identifying patterns. The best ways to do this are by constructing frequency and percent distributions.

A frequency distribution is an organized tabulation of the number of individuals or scores located in each category see the table below. From the table, you can see that 15 of the students surveyed who participated in the summer program reported being satisfied with the experience. A percent distribution displays the proportion of participants who are represented within each category see below. The most common descriptives used are:. Depending on the level of measurement, you may not be able to run descriptives for all variables in your dataset. The mode most commonly occurring value is 3, a report of satisfaction.

By looking at the table below, you can clearly see that the demographic makeup of each program city is different. You can also disaggregate the data by subcategories within a variable. This allows you to take a deeper look at the units that make up that category. In the table below, we explore this subcategory of participants more in-depth. From these results it may be inferred that the Boston program is not meeting the needs of its students of color.

This result is masked when you report the average satisfaction level of all participants in the program is 2. In addition to the basic methods described above there are a variety of more complicated analytical procedures that you can perform with your data. These include:. These types of analyses generally require computer software e. We provide basic descriptions of each method but encourage you to seek additional information e. A correlation is a statistical calculation which describes the nature of the relationship between two variables i. An important thing to remember when using correlations is that a correlation does not explain causation.

A correlation merely indicates that a relationship or pattern exists, but it does not mean that one variable is the cause of the other. An analysis of variance ANOVA is used to determine whether the difference in means averages for two groups is statistically significant. For example, an analysis of variance will help you determine if the high school grades of those students who participated in the summer program are significantly different from the grades of students who did not participate in the program.
