WHAT ARE STRING VARIABLES SPSS HOW TO

This setting will greyed out if Histograms is selected.Д Format: Opens the Frequencies: Format window, which contains options for how to sort and organize the table output. In particular, these options affect whether the labeling for the pie slices or the y-axis of the bar chart uses counts or percentages. Note that the options in the Chart Values area apply only to bar charts and pie charts. Pie chart depicts the categories of a variable as 'slices' of a circular 'pie'.Bar chart displays the categories on the graph's x-axis, and either the frequencies or the percentages on the y-axis.Histograms should only be used for continuous variables they should not be used for ordinal variables, and should never be used with nominal variables. For categorical variables, bar charts and pie charts are appropriate. Options include bar charts, pie charts, and histograms. In general, you should never use any of these statistics for dichotomous variables or nominal variables, and should only use these statistics with caution for ordinal variables.Д¬ Charts: Opens the Frequencies: Charts window, which contains various graphical options. It is up to the researcher to determine if these measures are appropriate for their data. SPSS will compute those statistics if they are requested, regardless of whether or not they are meaningful. If your categorical variables are coded numerically, it is very easy to mis-use measures like the mean and standard deviation. For example, this would be the case if you had measured subjects' ages and had coded anyone between the ages of 20 and 29 as 25, or between the 30 and 39 as 35 (source: IBM SPSS Statistics Information Center). The Values are group midpoints option can be applied to certain ordinal variables that have been coded in such a way that their value takes on the midpoint of a range.The Mode (which is the most frequent response) has a clear interpretation when applied to most nominal and ordinal categorical variables.The vast majority of the descriptive statistics available in the Frequencies: Statistics window are never appropriate for nominal variables, and are rarely appropriate for ordinal variables in most situations. Moving several variables to this box will create several frequency tables at once.Д« Statistics: Opens the Frequencies: Statistics window, which contains various descriptive statistics. To include a variable for analysis, double-click on its name to move it to the Variables box. To run the Frequencies procedure, click Analyze > Descriptive Statistics > Frequencies.ДЄ Variable(s): The variables to produce Frequencies output for. I recommend to save this into syntax by also do the command again and klick on the вЂњPasteвЂќ button so you can reuse the command.In SPSS, the Frequencies procedure can produce summary measures for categorical variables in the form of frequency tables, bar charts, or pie charts. Then you will see the new variables that is possible to use in factor analysis, correlations, calculation avarage and so on: So add all new codings until you are ready: When you have clicked on the button вЂњOld and New valuesвЂќ you will get this dialog box: You type in new variable names on your new variables, I have typed in att1 and att2. So I will recode these to number codes instead.Д¬hoose the command : Transform вЂ“ Recode into different variables ItвЂ™s in an Excel file, and when you get it over to SPSS it will automatically be string variables and you are very limited to do statistics on that: Here is my data example that is quite common to find when you recieve data from a study. I happens often that you get text answers from a websurvey, and in some cases itвЂ™s ok but if you want to do statistical analysis like correlation it will not work вЂ“ then you must convert them to numbers. Next Monday I will show you how easy it is to do an automatic recode of string variables to numeric variables, but you will get the alphabetic order and there were a user who asked for an own order of the recoding.
