What is the primary purpose of quantitative methods in business?
✔️✔️ Quantitative methods are used to support decision-making by analyzing numerical data,
identifying patterns, and optimizing solutions.
Define "probability" in the context of business decisions.
✔️✔️ Probability is a measure of the likelihood that a particular event will occur, helping businesses
anticipate outcomes and make informed choices.
How can descriptive statistics help in business analysis?
✔️✔️ Descriptive statistics summarize and describe data characteristics, making it easier to
understand key trends and inform decision-making.
What does it mean if two variables have a positive correlation?
✔️✔️ A positive correlation means that as one variable increases, the other also tends to increase,
indicating a direct relationship between them.
Explain what a "sample" is and why it’s used in statistics.
✔️✔️ A sample is a subset of a population, used because it’s often impractical or impossible to
analyze an entire population.
How does hypothesis testing support business research?
, ✔️✔️ Hypothesis testing evaluates assumptions or claims, allowing businesses to make conclusions
about data with a certain level of confidence.
What role does linear regression play in forecasting?
✔️✔️ Linear regression models the relationship between variables, helping forecast future values
based on past data.
Define "standard deviation" and its importance in data analysis.
✔️✔️ Standard deviation measures the spread of data around the mean, indicating data variability,
which is crucial for understanding data consistency.
What is a "time series" and why is it valuable for businesses?
✔️✔️ A time series is a sequence of data points collected over time, valuable for identifying trends
and seasonal patterns in business data.
How does decision analysis aid business managers?
✔️✔️ Decision analysis provides structured methods to evaluate complex choices, helping managers
select the best course of action.
What is meant by "optimization" in business analytics?
✔️✔️ Optimization is the process of finding the most efficient solution to a problem, maximizing or
minimizing key variables for best results.
Explain why businesses use simulation models.
