Frequency Tables and Relative Frequency

How do you calculate relative frequency?

• Relative frequency = (Frequency of a specific value) / (Total frequency) x 100%.

• Relative frequency = (Total frequency) / (Frequency of a specific value) x 100%.

• Relative frequency = (Frequency of a specific value) + (Total frequency) x 100%.

• Relative frequency = (Frequency of a specific value) - (Total frequency) x 100%.

How can frequency tables be used in real-life situations?

• To create visual art and designs

• In surveys, research, and data analysis to summarize and interpret data

• For cooking and recipe measurements

• To enhance video game graphics

What is the total frequency in a frequency table?

• The total frequency is the sum of all individual frequencies in the table.

• The total frequency is the highest frequency in the table.

• The total frequency is the lowest frequency in the table.

• The total frequency is the average of all frequencies in the table.

What does a high relative frequency indicate?

• A high relative frequency indicates that a particular value or category occurs frequently in the dataset.

• A high relative frequency suggests that the dataset is biased towards certain values.

• A high relative frequency means that the dataset has a large number of entries overall.

• A high relative frequency indicates that the data is normally distributed.

What is the importance of understanding relative frequency?

• It helps in comparing different categories within a dataset.

• It provides a method for calculating mean values.

• It is used to determine the mode of a dataset.

• It simplifies complex data into a single value.

What is relative frequency?

• The total number of values in a dataset.

• The ratio of the number of times a value occurs to the total number of values, often expressed as a percentage.

• The average of all values in a dataset.

• The difference between the highest and lowest values in a dataset.

If a frequency table shows 40 males and 60 females, what is the relative frequency of males?

• 30%

• 40%

• 50%

• 60%

How can you find the number of students who skipped breakfast from a frequency table?

• Look for the frequency corresponding to 'skipped breakfast' in the table.

• Count the total number of students in the table.

• Subtract the number of students who had breakfast from the total.

• Identify the students who reported skipping breakfast in a survey.

What is a frequency table?

• A method to calculate the mean of a dataset.

• A way to organize data that shows how often each value occurs in a dataset.

• A graphical representation of data using bars.

• A technique to find the median of a dataset.

If 15 students purchased no food out of 100 surveyed, what is the relative frequency of purchasing no food?

• 10%

• 15%

• 20%

• 25%
