Statistical Sampling and Analysis Techniques
Correlation Coefficients
Pearson Correlation Coefficient (r)
Measures the strength and direction of the linear relationship between two continuous variables.
Key Characteristics
- Range: r values range from -1 to +1.
- r = +1: Perfect positive linear relationship.
- r = -1: Perfect negative linear relationship.
- r = 0: No linear relationship.
Formula: 
Assumptions: Variables are continuous and normally distributed. The relationship between variables is linear. No significant outliers.
Applications: Assessing the

Calculation Result from the Variation of Equity: If we compare the PN of a company in two different periods of time, we see that it has changed. If the company evolves so that the CP increases, it is said to have obtained benefits; if the value of PN decreases, it is said that the company has had losses during this period.

1) Operating Activities: The indirect method for preparing the statement of cash flows involves adjusting net income with changes in balance sheet accounts to determine cash generated from operating activities.
2) Investing Activities: Cash flows from investing activities are crucial, representing a significant source or use of cash, especially in capital-intensive industries like manufacturing. Persistent negative cash flows for fixed assets may indicate growth and expected returns on investments.

The Basic Research Process
Quantitative research involves formulating a problem, developing assumptions (hypotheses), and defining variables. The process includes analyzing variable distribution, examining cross-variable relationships to test hypotheses, and conducting a comprehensive analysis using tables and graphs.
Festinger and Katz’s Sample Survey Development
- Establish the problem and define overall objectives.
- Specify data objectives and assumptions.
- Define sample type, size, and composition.
- Design
