Two-Way Frequency Tables Flashcard Retake

Front

What is a two-way frequency table?

Back

A two-way frequency table is a statistical tool that displays the frequency of different outcomes in two categorical variables, allowing for the analysis of the relationship between them.

How do you calculate the percentage from a frequency table?

Back

To calculate the percentage, divide the frequency of the specific category by the total frequency and multiply by 100.

Front

What does relative frequency represent?

Back

Relative frequency represents the ratio of the number of times an event occurs to the total number of trials or observations.

Front

What is the formula for probability?

Back

Probability = (Number of favorable outcomes) / (Total number of outcomes).

Front

How can you determine which option is most profitable in a survey?

Back

Analyze the frequency of each option and choose the one with the highest frequency or percentage.

Front

What is the significance of rounding in probability?

Back

Rounding in probability helps to simplify the representation of a number, making it easier to interpret, especially when dealing with decimals.

Front

What does it mean if a percentage is greater than 100% in a frequency table?

Back

A percentage greater than 100% indicates an error in calculation or that the data is not properly normalized.

Front

How do you interpret a percentage in the context of a survey?

Back

A percentage in a survey indicates the proportion of respondents who selected a particular option relative to the total number of respondents.

Front

What is the relationship between two-way frequency tables and probability?

Back

Two-way frequency tables can be used to calculate probabilities by analyzing the frequencies of different outcomes.

What is the importance of sample size in surveys?

Back

A larger sample size generally leads to more reliable and valid results, reducing the margin of error.
