(Baht) 3.6 The statistics are used to analyse the data.Data analysis is divided into two parts: a complex statistics to describe complex statistics and data processing, and to infer.Use statistical analysis to help in the finished3.6.1 strategic statistical description (Descriptive Statistics)As the statistics that are used to summarize the basic characteristics of each variable, i.e. frequency and percent (Frequency and.Proportion) the average (Mean), maximum value (Maximum) the minimum value of the data (Minimum) and.Standard deviation (Standard Deviation) to measure the distribution of the data.3.6.2 (Inferential Statistics) in statistics, quantitative assumes.By analyzing the relation by analyzing the correlation coefficient (Pearson's Correlation of Pearson.Coefficient) to measure the relationship between the independent variables and the variable is called the correlation coefficient.(Pearson's r – in) and a significant test to statistical decision analysis regression equation and the multiples.(Multiple Regression Analysis) is the official statistical analysis techniques. To determine the relationship of each variable byTo predict one variable from the variable, and the variable control to learn how to use these variables will help explain.Changes of variables as independent variables are used more, and consideration by the statistical assumptions.According to the hypothesis, when the significance level there was less than a given significance level was 0.05 and directions.The relationship from the strategic focus on regression coefficient value (Coefficient).
