What type of graph is best for displaying the growth of multiple vegetables over time?

Front

What is the mean of a data set?

Back

The mean is the average value of a data set, calculated by adding all the numbers together and dividing by the total count of numbers.

Front

What is an inference?

Back

An inference is a conclusion drawn from evidence or reasoning rather than from explicit statements. It goes beyond what is directly observed.

Front

What type of graph is best for comparing average heights across different classes?

Back

A multiple bar graph is best for comparing average heights across different classes, as it allows for easy comparison of different groups.

Front

What is a quantitative observation?

Back

A quantitative observation is a measurement that involves numbers and can be quantified, such as height, weight, or temperature.

Front

What is the difference between mean, median, and mode?

Back

Mean is the average, median is the middle value when data is ordered, and mode is the most frequently occurring value in a data set.

Front

What is a hypothesis?

Back

A hypothesis is a testable statement or prediction about the relationship between variables, often formulated before conducting an experiment.

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set, indicating the spread of the data.

Front

What is a pie chart used for?

Back

A pie chart is used to represent data as parts of a whole, showing the relative proportions of different categories.
