Precision, Accuracy, and Graphing

Which term describes measurements that are precise?

• Accuracy

• Precision

• Graphing

• Interpolation

What is the definition of accuracy?

• Measurements are precise if they have a small range of values.

• Measurements are accurate if they are close to the true value.

• Measurements are accurate if they have a large range of values.

• Measurements are precise if they are close to the true value.

• Bar graph

• Line graph

• Pie chart

• Scatter plot

What is the purpose of a line graph?

• To compare different categories of data.

• To show the relationship between two variables.

• To display data in a circular format.

• To represent data using bars of different heights.

What does a best fit line on a graph allow you to do?

• Interpolate data

• Extrapolate data

What is the definition of a bar graph?

• A bar graph is a type of exercise equipment used for weightlifting.

• A bar graph is a graphical representation of data using rectangular bars of different heights or lengths to represent different quantities or categories.

• A bar graph is a mathematical equation used to solve complex problems.

• A bar graph is a type of musical instrument.

What is the purpose of a scatter plot?

• To compare multiple variables.

• To show the distribution of a single variable.

• To display the trend of a single variable over time.

• To display the relationship between two variables.

What is the difference between accuracy and precision?

• Accuracy is the closeness of a measured value to the desired value, while precision is the closeness of the measured values to the average value.

• Accuracy is the closeness of a measured value to the average value, while precision is the closeness of the measured values to the true value.

• Accuracy is the closeness of a measured value to the true value, while precision is the closeness of the measured values to each other.

• Accuracy is the closeness of a measured value to the predicted value, while precision is the closeness of the measured values to each other.

What is the definition of a line graph?

• A line graph is a type of chart that displays information as a series of data points connected by bars.

• A line graph is a type of chart that displays information as a series of data points connected by curved lines.

• A line graph is a type of chart that displays information as a series of data points connected by dotted lines.

• A line graph is a type of chart that displays information as a series of data points connected by straight line segments.

What is the purpose of a bar graph?

• To display data in a linear format

• To visually represent and compare data in different categories or groups.

• To represent data in a pie chart format

• To show the relationship between two variables
