A statistical table contains several components designed to illustrate the data, including a title for the table, the table number, the heading and subheadings, the table body, the table spanner, dividers and table notes. Tables are used to display data obtained from an experiment and are often included in lab reports or research papers and presentations.Know More
The title of the table provides a description of the contents. It may include the groups, their classifications and the variables. The title should never be more than one or two lines. Table numbers are needed to refer to a specific set of values being discussed. This is especially useful if there are multiple tables.
Headings and subheadings identify and establish the order of the data. Column headings and column spanners are included in headings and subheadings. The table body is where the bulk or meat of the data is located. This includes any means, percentages, frequencies or other values found that are significant. Table spanners divide data in a table without the addition of another column. Dividers are horizontal lines that separate different parts of the table. Finally, table notes explain any information that is included in the table, including definitions and abbreviations.Learn More
R-squared is used for linear regression analysis by transforming the dependent variable in a regression model that is fitted to a particular set of data. In order to use R-squared on a specific regression model, a statistician may have to start with other transformations such as logging and deflating so as to eliminate unnecessary variability caused by factors such as inflation. These transformations explain a significant amount of variance.Full Answer >
Sample mean is calculated by finding the sum of all terms in the selected sample and dividing this figure by the total number of terms. This formula is used to compute the average of the data collected.Full Answer >
In mathematics, particularly in the field of statistics, the mode is the value that occurs most often in a series of numbers. It is also referred to as the modal value. If a set of data values does not have a repeating number, then it has no mode.Full Answer >
Parametric testing is defined by making one or more assumptions about the population's properties. The most common assumptions to make are that the population will be normally distributed or have data based on an equal-interval scale.Full Answer >
