What is a graphic representation of a frequency distribution contructed by erecting vertical bars?
A bar graph.
Is a frequency polygon plotted in the middle?
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.
What kind of chart uses rectangles to show frequency distribution?
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.
What are some advantages of using a histogram over a polygon?
Histograms provide a clear visual representation of data distribution by displaying the frequency of data points within specific intervals, making it easier to identify patterns and trends. They effectively illustrate the shape of the data distribution, such as skewness and modality. In contrast, polygons can be less intuitive for quickly assessing the frequency of data, as they require connecting midpoints of intervals, which can obscure individual frequency counts. Additionally, histograms handle large data sets more effectively by aggregating data into bins, simplifying the visualization.
What is the name for a relative frequency distribution shown by heights?
Are you talking about a histogram of the relative frequency distribution.
What is A graphic representation of a frequency distribution constructed by connecting the class midpoints with lines?
This is called a frequency polygon.
What is a graphic representation of a frequency distribution contructed by erecting vertical bars?
A bar graph.
When drawing frequency distribution histograms what does it mean when the distribution is broken?
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.
Is a frequency polygon plotted in the middle?
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.
What graph is used when data is condensed into a frequency table?
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.
What is derived frequency distribution?
It is derived frequency distribution. XD
What is the difference of frequency distribution and relative frequency distribution?
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
What is a pictorial representation of the frequency table?
A pictorial representation of a frequency table is called a histogram.
What is the cumulative column frequency distribution table?
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.
What kind of chart uses rectangles to show frequency distribution?
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.
What are the disadvantages of frequency distribution in points?
What are the disadvantages of frequency distribution tables
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
