To describe the basic statistics information.To explain or describe the preliminary statistical data with the information collected, brought the action to represent a group of data.Preliminary statistics available values are used to describe or narrate the group information in the form of a summary, rather than all the data presented. The data is taken for preliminary statistics can be used in both demographics (Population) and the sample data (Sample)The information that will be required for basic statistics as a measure is the ratio or interval. Some cases may be used to sort the top level information.Preliminary statistics for characterization of 4-way.1. find the trend into a central (Central Tendency). The average (Mean), such as:The arithmetic average (Arithmetic Mean or Average, A.M), The geometric average (Geometric Mean, F.M), The average harmony (Harmonic Mean, H.M) The mode (Mode). The value of the data (N-Tiles), such as the median (Median), quartile (Quartiles), De Zeil (Deciles) and percentage (Percentiles) tile.2. the data distribution (Dispersion). Radar (Range) Quartile deviation (Quartile Deviation). Average deviation (Mean Deviation). The standard deviation (Standard Deviaion) Coefficients of variations or distribution (Coefficient of Variation).3. the standard score (Standard Score). 4. an value shows the shape of the curve., frequency (Frequencies, the Distribution Curve). A normal curve (Normal Curve). Curved bed (Skewness Curve), such as the curved arch bed right bed left,Analysis of basic statistics.To create a one-way frequency distributionAs the distribution of information by one of the styles on a single feature or only recognizes the value of data by using a single variable.For example, to know the frequency of the level of education.3. open the file data.sav 4. Select Descriptive Statistics-Analyze-> menu > Frequencies. The preliminary statistics are not classified in groups.From the DATA.sav file in a variable that can be calculated are age, income.For example, calculate the value of basic statistics. The variable age.Descriptive Statistics-Analyze-> selection > Descriptives
