To calculate correlation coefficients
To conduct factor analysis
#4
What is the purpose of a pilot study in behavioral research?
To conduct the main analysis
To gather initial data and test research procedures

#7
What is the main purpose of inferential statistics in behavioral trend analysis?
Summarize and describe data
Make predictions or inferences about a population
Calculate percentages
Identify patterns in data
#8
Which statistical measure is most appropriate for describing the central tendency of a skewed dataset?
#9
What does the term 'standard deviation' represent in statistical analysis?
The average value in a dataset
The spread or dispersion of values around the mean
