Let’s add variable labels to the following:įinally, specify missing values for RELIGID as 0, 8, and 9 and EDUC as 99 and 98.
SPSS HISTOGRAM SOFTWARE
With the right software (such as SPSS), you can create and inspect histograms very fast and doing so is an excellent way for getting to know your data. In our opinion, histograms are among the most useful charts for metric variables. If you want to be able to save and store your charts for future use and editing, you must first create a free account and login - prior to working on your charts. This has possible values of 0 (inapplicable), 1 (white), 2 (black), 3 (other). This tutorial aimed at explaining what histograms are and how they differ from bar charts. × You are not logged in and are editing as a guest. The number ranges depend upon the data that is being used. The vertical axis (frequency) represents the amount of data that is present in each range. The horizontal axis displays the number range.

Setting these values will allow SPSS to correctly treat these values as missing in the analysis.

A histogram is the graphical representation of data where data is grouped into continuous number ranges and each range corresponds to a vertical bar. We can add this as a value label, which will show up on any tables or figures that we create.įor missing values, there is an automatic “System Missing” value of “.”, but some files use numeric values, e.g. -999, to represent missing responses. For example, the SEX variable is coded as 1s and 2s, where 1 represents male and 2 represents female. In addition to variable labels, value labels can also be very useful when dealing with categorical data. Variable labels are helpful so that the output is easy to read. SPSS does not allow spaces or special characters in variable names. Role: An optional setting to indicate how the variable will be used in analysisĬhanging a variable name is very easy simply double click on the cell with the name you want to change, and type in the new name.Īdding variable labels can be done similarly.Measure: Indicates if the variable is scale, ordinal, or nominal.Align: Specifies whether data are left, right or center aligned.Missing: Whether any values are set to missing.Label: A descriptive label for the variable.Decimals: How many decimals to round numeric entries to.Width: Upper limit of how many characters are in each entry.Type: Specifies if the variable is numeric, string, date, etc.The columns, from left to right, are as follows:
