    SPSS research analyzes central tendency and standard deviation with the aim of coming up with close examined results of the data which can guide the researcher for further analysis using the appropriate analyzing tools. The central tendency consists of mean, median and mode which describe the location of the distribution while standard deviation measures the dispersion i.e. the variation from the mean.

    SPSS researchers can know several interesting things from central tendency analysis. For instant, location of the distribution is symmetrical (normally distributed) when the values of mean and median are almost equal and asymmetrical when the two values have a great different.

    Comparing mean and standard deviation on several groups, SPSS researcher can be able to make a good conclusion by making decision of certain scenario whereby means with small variation can mean a lot than those with large variation.

    There are several ways to make SPSS research analyze central tendency:
    I will give two ways of the procedure.
    From Analyze menu
    Descriptive statistics, Frequencies…. On the dialog that appears select the variables you want analyze and then click on the statistics button. Another dialogue appears where you check on the boxes of mean, median, mode and sum under central tendency and standard deviation under dispersion, , click continue and lastly ok on previous dialog box.

    Another procedure is:
    From Analyze menu
    Descriptive statistics, Descriptives… On the dialog that appears select the variables you want analyze and then click on the options button. Another dialogue appears where you check on the boxes of mean and sum and standard deviation under dispersion, click continue and lastly ok on previous dialog box.
