Question,Answer A,Answer B,Answer C,Answer D,Answer Info (+ Explanation) Which type of data is best represented using a bar chart?,Continuous data,Categorical data,Ordinal data,Discrete quantitative data,"B) Categorical data. Bar charts are used to display categorical data, where each bar represents a category, and the height indicates the frequency or count." What is the key difference between a bar chart and a histogram?,"Bar charts are used for continuous data, while histograms are used for categorical data.","Histograms have gaps between the bars, but bar charts do not.","Bar charts can show categorical data, while histograms show the distribution of quantitative data.","Bar charts show data changes over time, while histograms show frequencies.","C) Bar charts can show categorical data, while histograms show the distribution of quantitative data. Bar charts help compare categories, while histograms show frequency distributions." "When reading a histogram, what does the height of each bar represent?",The percentage of each category.,The number of intervals on the x-axis.,The frequency or count of values within each interval.,The sum of values in the dataset.,C) The frequency or count of values within each interval. The height indicates how many data points fall within that interval. Why might someone use a stem plot instead of a histogram for a small dataset?,A stem plot shows each individual data point while maintaining the distribution.,A stem plot works better for ordinal data.,A stem plot can handle large datasets better.,A stem plot can only show categorical data.,A) A stem plot shows each individual data point while maintaining the distribution. Stem plots are useful for small datasets where individual values matter. "In a stem plot, if the data value is 157, how would you write the stem and leaf?",Stem: 1 \| Leaf: 57,Stem: 15 \| Leaf: 7,Stem: 157 \| Leaf: 0,Stem: 10 \| Leaf: 57,"B) Stem: 15 \| Leaf: 7. In a stem plot, the stem represents all but the last digit, and the leaf is the last digit." Which type of plot is most suitable for showing how a variable changes over time?,Bar chart,Stem plot,Histogram,Time plot,D) Time plot. Time plots show how a variable changes over time by plotting time on the x-axis and the variable on the y-axis. "If a teacher wants to compare the test scores of two classes side by side, which type of plot would be most suitable?",Stem plot,Back-to-back stem plot,Histogram,Pie chart,B) Back-to-back stem plot. This plot type is designed to compare two distributions side by side using the same set of stems.
