What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What does it mean to conduct a simulation in statistics?

Back

A simulation in statistics is a method used to model the behavior of a system by generating random samples to estimate probabilities and outcomes.

Front

What is a trial in the context of a simulation?

Back

A trial is a single instance of an experiment or simulation, where outcomes are recorded to analyze results.

Front

What is the significance level in hypothesis testing?

Back

The significance level, often denoted as alpha (α), is the threshold for determining whether to reject the null hypothesis, commonly set at 0.05.

Front

What does it mean to have convincing evidence at the 5% significance level?

Back

It means that the probability of observing the results, assuming the null hypothesis is true, is less than 5%, indicating strong evidence against the null hypothesis.

Front

What is the difference between 'at most' and 'at least' in probability?

Back

'At most' refers to a maximum limit (e.g., 4 or fewer), while 'at least' refers to a minimum limit (e.g., 5 or more).

Front

How do you interpret a probability of 0.06?

Back

A probability of 0.06 indicates that there is a 6% chance of the event occurring.

Front

What does it mean if an event is considered unusual in statistics?

Back

An event is considered unusual if its probability is significantly low, often below the 5% significance level.

Front

What is the role of trials in estimating probabilities?

Back

Trials help estimate probabilities by providing empirical data on how often an event occurs in repeated experiments.

Front

What is the importance of sample size in simulations?

Back

A larger sample size generally leads to more accurate estimates of probabilities and reduces variability in results.
