The graphical representation you are describing is known as a histogram. In a histogram, the vertical rectangles (or bars) represent the frequency of data within specific intervals (or bins), and the centers of the bases of these rectangles align with the class marks of the data. The height of each rectangle corresponds to the frequency of observations within each class interval, visually illustrating the distribution of the dataset.
A histogram uses rectangles to represent the frequency distribution of a dataset. In a histogram, the width of each rectangle corresponds to the interval of values (bins), while the height indicates the frequency of data points within that interval. This visual representation helps to identify patterns, such as the shape of the distribution, central tendencies, and variability within the data.
A bar graph.
Yes, a frequency polygon is typically plotted by connecting points that represent the midpoints of each class interval in a frequency distribution. The points are plotted above the midpoints, with the frequency on the vertical axis and the class intervals on the horizontal axis. This visualization helps to show the shape of the distribution of the data. The polygon is often closed by connecting the endpoints to the horizontal axis at the minimum and maximum class intervals.
It is usually called the axis for the independent variable.
A histogram represents the distribution of scores in a dataset by organizing them into equally spaced intervals or bins along the horizontal axis, and displaying the frequency or count of scores within each bin on the vertical axis. The scores on the horizontal axis could be any type of numerical data, such as test scores, heights, or ages.
A histogram is "a representation of a frequency distribution by means of rectangles whose widths represent class intervals and whose areas are proportional to the corresponding frequencies.Broken distribution means that no data point falls in that class.

A histogram is used when data is condensed into a frequency table. It displays the frequency of data within fixed intervals or bins, providing a visual representation of the distribution of the data.
It is derived frequency distribution. XD
A frequency distribution lists each value in the distribution and the number times it appears, while a relative frequency distribution reports the proportion of cases reporting each value
A pictorial representation of a frequency table is called a histogram.
Cumulative Frequency is The total of a frequency and all frequencies so far in a frequency distribution. It is the 'running total' of frequencies in the frequency distribution table.
