Question,Answer A,Answer B,Answer C,Answer D,Answer Info (+ Explanation) Why would you choose a pie chart over a bar chart to represent data?,To show the count of each category.,To display how each category relates to the whole.,To compare the frequency of each category.,To show changes in a category over time.,B) To display how each category relates to the whole. A pie chart is used to show the proportion of each category as part of the entire dataset. What is the key advantage of using a time plot instead of a bar chart?,"Time plots can show changes over time with trends, while bar charts cannot.",Time plots can only be used for ordinal data.,Bar charts are better at showing frequency distributions.,Time plots are used for categorical data representation.,"A) Time plots can show changes over time with trends, while bar charts cannot. Time plots are designed to show how a variable evolves over a period of time." "When creating a histogram, which convention is typically followed for intervals?",The right endpoint of each interval is included.,Both endpoints of each interval are included.,The right endpoint of each interval is excluded.,There are no specific conventions to follow.,C) The right endpoint of each interval is excluded. This convention helps maintain consistency and prevents overlapping values between intervals in a histogram. What is a common reason to split stems in a stem plot?,To make the plot larger for easier visibility.,To reduce the number of leaves per stem when there are too many.,To convert categorical data to numerical data.,To include decimal places in the plot.,B) To reduce the number of leaves per stem when there are too many. Splitting stems improves readability when there are too many data points in a single stem. A researcher wants to show the relative frequency of age groups in a population. Which type of histogram should they use?,Cumulative histogram,Bar chart,Relative frequency histogram,Stem plot,"C) Relative frequency histogram. This type of histogram shows the proportion of values in each interval relative to the total, making it ideal for visualizing the relative frequency of different groups."
