1. In a .........., the height of each column is proportional to the number of candidates falling into the correspond.

• Answer: c. histogram
  A histogram visually represents frequency distributions, where the height of each bar (column) corresponds to the number of observations (candidates) within each interval.

• Answer: b. histogram
  A histogram is specifically designed to display the frequencies of data points in specified intervals, with bars representing the frequency of each interval.

3. A graph similar to a frequency histogram except that frequencies are represented by points and the points are connected by a line is called a ...........

• Answer: c. frequency polygon
  A frequency polygon is created by plotting points representing the frequencies at the midpoint of intervals and connecting those points with straight lines, providing a visual representation of the distribution.
