A dot plot is similar to which other type of graph, but with more emphasis on individual data points? (A) Bar Chart (B) Histogram (C) Line Graph (D) Pie Chart
Answer (1)
A dot plot is similar to a histogram but with more emphasis on individual data points. The correct choice is (B) Histogram.
Here's why:
A dot plot is a type of data display that uses dots to represent each data point. Each dot corresponds to one observation, and they are stacked in a column over a number line, making it easy to see the frequency of values in the dataset. This focus on individual data points is ideal for small to medium-sized datasets.
A histogram , on the other hand, is a graphical representation of the distribution of numerical data. It is an estimate of the probability distribution of a continuous variable, using bars to show the frequency of data intervals or bins.
Similarities : Both dot plots and histograms display the distribution of data. They help visualize the shape, spread, and central tendency of the data set.
Differences : A dot plot represents individual data points explicitly, while a histogram summarizes data into bins and uses bars to show frequency. This makes histograms better for representing large datasets.
Therefore, considering that a dot plot emphasizes individual data points, option (B) Histogram is the answer, as both are used to present frequency data but with different focuses.
