    A "missing value" in SPSS represents a known datapoint with an unknown value. In other words, if you had an SPSS dataset with hourly temperature data, but the probe was inoperable for a four hour span one day, you'd still want the data points (one for each hour), but the temperature value would be missing. This can be crucially important for proper statistical distribution.
