Why are unequal class intervals sometimes used in a frequency distribution?
Usually because the frequencies at one or both ends of the distribution are very small.
Why are unequal class intervals used in frequency distribution?
To make the graph symmetrical
What does cumulative frequency graph measure?

Why are unequal class intervals sometimes used in Frequency distribution?
Because sometimes adjacent classes have to be merged so that the frequencies are not too small. This is important if anonymity is to be preserved. It is also important for statistical testing.
What is the difference between stated and real class limits?
Real Class Limits are the class intervals of a frequency distribution when stated as in continuous categories. ie. 18.5-19.5, 20.7-34.7 Stated Class Limits are the class intervals of a frequency distribution when stated as discrete categories. ie. 19-21, 23-25
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.
What is a sentence for class interval?
class interval - one of several convenient intervals into which the values of the variate of a frequency distribution may be grouped.
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.
How do you find out the cumlative frequancy?
Cumulative frequency is found by adding the frequency of each class interval to the sum of the frequencies of all previous intervals. To calculate it, you start with the first interval, where the cumulative frequency is simply the frequency of that interval. For subsequent intervals, you add the frequency of the current interval to the cumulative frequency of the previous interval. This process continues until all intervals are accounted for, resulting in a cumulative frequency distribution.
How is a frequency distribution converted to a relative frequency distribution?
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
In a frequency distribution what is the number of observation in a class called?
Class Frequency
What are the Steps involved in construction of frequency distribution table?
To construct a frequency distribution table, follow these steps: Collect Data: Gather the raw data that you want to analyze. Determine Class Intervals: Decide on the number of classes and the range for each class interval, ensuring they cover the entire data set without overlap. Tally the Frequencies: Count how many data points fall into each class interval and record the frequency for each. Create the Table: Organize the class intervals and their corresponding frequencies into a structured table format for easy reference and analysis.
What is the difference between class intervals and class width in statistics?
Oh, dude, class intervals are the ranges that group data together in a frequency distribution, like 1-10, 11-20, etc. Class width is just the difference between the upper and lower boundaries of each class interval. So, basically, class intervals are like the neighborhoods where data hangs out, and class width is just the size of the houses in those neighborhoods.
