Explain the concept of misleading graphs.

• Misleading graphs are graphs that are designed to distort or manipulate data in order to mislead or deceive the viewer.

• Misleading graphs are graphs that are commonly used in scientific research.

• Misleading graphs are graphs that are created to highlight the most important data points.

• Misleading graphs are graphs that are used to present data in a clear and accurate manner.

How are weighted averages calculated?

What is the purpose of a box and whisker plot?

• The purpose of a box and whisker plot is to display the distribution of a dataset and identify outliers.

• The purpose of a box and whisker plot is to compare two different datasets.

• The purpose of a box and whisker plot is to display the mean and median of a dataset.

• The purpose of a box and whisker plot is to show the relationship between two variables.

Give an example of a misleading graph and explain why it is misleading.

• A pie chart that uses different colors to represent the same category, making it difficult to compare the proportions.

• A line graph that uses a different unit of measurement on the x-axis, distorting the relationship between the variables.

• A scatter plot that excludes data points that do not fit the desired trend, giving a false impression of correlation.

• An example of a misleading graph is a bar graph that uses a different scale on the y-axis, making the differences between the bars appear larger than they actually are.

Calculate the weighted average of the following data: [3, 4, 5, 6] with weights [0.1, 0.2, 0.3, 0.4].

• 4.5

• 4.8

• 5.5

• 5.0

What information can you gather from a box and whisker plot?

• The information that can be gathered from a box and whisker plot includes the standard deviation and variance.

• The information that can be gathered from a box and whisker plot includes the mean and mode.

• The information that can be gathered from a box and whisker plot includes the minimum and maximum values, the median, and the quartiles.

• The information that can be gathered from a box and whisker plot includes the range and interquartile range.

Explain the concept of outliers in box and whisker plots.

• Data points that are missing from the plot

• Data points that are within the normal range

• Data points that are randomly selected

• Data points that are significantly different from the rest of the data
