How do you find the mode in a set of data?

Back

The mode is the number that appears most frequently in a dataset.

Front

What does it mean if a dot plot has a peak?

Back

A peak in a dot plot indicates the value that has the highest frequency, meaning the most students solved the puzzle in that time.

Front

How can you determine how many students solved a puzzle in less than a certain time using a dot plot?

Back

Count all the dots to the left of the specified time on the dot plot.

Front

What is the purpose of using a frequency table?

Back

A frequency table helps to summarize and organize data, making it easier to see patterns and trends.

Front

If 17 students solved a puzzle in less than 15 minutes, what does this tell you about the data?

Back

It indicates that a significant number of students were able to solve the puzzle quickly.

Front

How do you interpret the data from a dot plot?

Back

Look for the number of dots above each value to understand how many students fall into each category.

Front

What is the difference between a dot plot and a bar graph?

Back

A dot plot uses dots to represent individual data points, while a bar graph uses bars to show the frequency of data in categories.

Front

How can you find the total number of students from a frequency table?

Back

Add up all the frequencies in the table to get the total number of students.
