Essay about Exploring Correlation And Regression Of Spss
Using the explore function within SPSS gives a clearer view of how the data is represented. The explore function helps to assess the variables within the investigation by visually identifying various aspects of the data, therefor revealing the true nature of the data (Field, 2013). For example, the data in the Chamorro-Premuzic.sav file can be evaluated in a number of ways, for example analyzing the data based on the gender grouping allow one to visualize the data by manipulating the data using gender as a factor, then placing the remainder of the values as dependent variables. Evaluating the data in this way gives the investigator a better understanding of how the data is either normally distributed or perhaps skewed (Triola, 2008) .
As identified in the case summery below, this is just one table of information available from SPSS explorer function. As seen here it helps to identify number of valid or missing case data as well as the percent as it concern each case. In addition, it provides information such as skewness and kurtosis that helps understand the level of spread surrounding the point of normality if present. Other components derived from the use of this function are range, standard deviation, variance, mean, median, and interquartile etc.
The analysis of this data help to provide guidance in determining the most appropriate technique of investigating and presenting the data effectively. There are a number graphs…
