Presentation transcript:

Additional roles include the following: ► ► Group analysis by Separate descriptive statistics are generated for each group. The groups are determined by the values of the variable that you assign to this role. ► ► Frequency variable A variable whose value represents the number of times the row should be counted. ► ► Relative weight variable A variable whose value for each row is used to calculate weighted means, variances, and sums. ► ► Copy Variable The variables that you assign to this role are included as additional variables in the output data set.

Fundamental Statistical Concepts ► ► Decide what tasks to complete before you analyze your data. ► ► Distinguish between populations and samples.

Defining the Problem Before you begin any analysis, you should complete certain tasks. 1. Outline the purpose of the study. 2. Document the study questions. 3. Define the population of interest. 4. Determine the need for sampling. 5. Define the data collection protocol.

Describing Your Data When you describe data, your goals are the following: ► ► Screen for unusual data values. ► ► Inspect the spread and shape of continuous variables. ► ► Characterize the central tendency. ► ► Draw preliminary conclusions about your data.

Hypothesis Testing ► ► Select the RISECEREAL data set in the Process Flow or Project Explorer. ► ► select Describe -> Distribution Analysis…. ► ► With Task Roles selected on the left, drag and drop weight to Analysis variables. ► ► Select Tables on the left. Deselect the boxes for Basic confidence intervals and Basic measures. ► ► Highlight Tests for location and change the H0: Mu = value to 15.
