Study Notes
Causal Research
- One variable influences another, either directly or indirectly, in a causal relationship.
- An illustration of a causal relationship is when a brick falls on a toe, causing pain and an involuntary scream.
- Causal relationships can be unidirectional (A influences B, but not vice versa) or bidirectional (each variable influences the other).
- Exercise and body weight have a bidirectional relationship: exercise influences body weight, and body weight influences exercise.
Strengths of Causal Research
- It identifies the causes behind processes, helping researchers fix problems or optimize outcomes.
- It provides benefits of replication if needed.
- Causal research identifies the impacts of changing processes and existing methods.
- Subjects are selected systematically, increasing internal validity.
Limitations of Causal Research
- Administering causal research is difficult due to the challenge of controlling extraneous variables.
- It is one of the most expensive research methods to conduct, sometimes costing millions.
- Causal research outcomes might reveal plans to competitors, allowing them to enter the market first.
- Confirmation requires additional research beyond causal research alone.
Correlational Research
- A primary goal is to determine if two or more variables covary and to establish the relationships observed.
- It involves observing variables "as is" without manipulation.
- An example includes determining the relationship between pretest anxiety and test performance by having students rate their anxiety and then comparing it to test scores.
- Variable comparisons occur across preformed groups based on participant characteristics like political affiliation or age.
- Group membership relies on participant choice, not researcher manipulation; party affiliation is measurable, but it cannot be changed.
- GPA can be predicted with student SAT scores, this allows determining the value between variables.
- The predictor variable is used to predict, while the criterion variable is being predicted.
- Causation between variables remains an open question.
Strengths of Correlational Research
- Researchers can collect more data than with experiments.
- Results are more applicable to everyday life because the research occurs outside the lab.
- It opens avenues for further scholarly research.
- It provides a good start to investigating phenomena and relationships and helps narrow findings or determine causation.
Limitations of Correlational Research
- It only uncovers relationships without conclusive reasoning for why they exist.
- It does not reveal which variable influences the other.
- A third, unknown variable could cause both correlating variables and reasons assumed be true.
Experimental Research Characteristics
- Manipulation of independent variables and control of extraneous variables form its defining characteristics.
- Values for independent variables are chosen by the experimenter.
- The set values are the levels of the independent variable.
- Sleep deprivation's effect on memory forms an example, participants are assigned to groups with 0, 24, or 48 hours of sleep deprivation.
- Exposing participants to variable levels is necessary to manipulate variables.
- Conditions linked to each level create the experiment's treatments.
- The independent variable is manipulated by exposing different groups to treatments or exposing all participants to treatments in sequence.
- Researchers hope to show that changes in an independent variable's level cause behavior changes.
- Value observed in designs determines the dependent variable.
- In a causal relationship, the level of the independent variable determines the value to some extent.
Control Over Extraneous Variables
- Experimental research involves regulating variables not of interest
- For instance, determining how anxiety therapy affects anxious students and degree can be determined.
- Uncontrolled extraneous variables lead to uncontrolled changes and hard to detect effects.
- Uncontrolled variability may produce chance differences, this makes it appear as though the effects came from the independent variable.
- Extraneous variables are controlled by holding them constant or randomizing effects across treatments.
Strengths of Experimental Approach
- Establish and describe causal relationships.
- The correlational approach can only indicate changes in one variable correspond with changes in another.
Limitations of Experimental Approach
- The method cannot be used to manipulate hypothesized variables.
- Studies on personality relies on correlational approaches to identify possible causal relationships.
- Exposing people to severe conditions to show the causes for personality disorder is unethical.
- Revealing the effect entails tight control over extraneous factors.
- The ability to apply findings to situations is reduced.
- Ability to establish causal relationships is decreased.

Financial Analysis
- Financial analysis helps to evaluate businesses, budgets, etc.
- The analysis helps determine performance and suitability.
- Analysis are used to analyze whether a company is solvent.
- It is used to evaluate business trends, while a financial analyst examines statements.
- A common way to analyze financial data is to calculate financial data.
Working Capital Ratio
- Dividing current assets by current liabilities to assess its liquidity.
- Liquidity helps determine how easily a company can cover short term investments.
Quick Ratio
- Also called the acid test, this ratio subtracts inventories, and can divide them into liabilities.
- This assists to show current liabilities that are covered by cash.
Earnings Per Share
- EPS measures income that is earned on shares.
- The analyst divides net income by the average.
Price-Earnings Ratio
- Called P/E, and shows future earning investments on investors.
- The company helps determine their stock price.
Debt-Equity Ratio
- This can reduce margins behind what it owes.
- This can also jack up fixed charges.
Return on Equity
- Calculated by taking net earnings (after-tax), subtracting dividends, then dividing into common equity.
- Common share holders determine how profitable the company is.
Competitor Analysis
- Those who compete for the customer is who the analyst needs to place competitors.
- List their marketing structure/tactics. Relevant questions:
- What are their strategies.
- What media is purchased for advertising.
- How can they be a threat.
Questionnaire Design
- A questionnaire is formalized and a pre-specified set of questions that help reflect objective investigation.
- Consumer attitudes needs to be measured.
Principles of Wording
Relating to factors:
- The nature of questions being asked.
- Beliefs and attitudes measured.
