bar graph
"Bar graph" is the word for the relative frequencies shown by heights.
Are you talking about a histogram of the relative frequency distribution.
In a relative frequency distribution, the relative frequencies should add up to 1 (or 100% when expressed as percentages). This represents the entire dataset, indicating that all possible outcomes have been accounted for. If the relative frequencies do not sum to 1, it suggests that there may be an error in the calculations or data collection.
The sum of a complete set of relative frequencies will be 100.
The sum of the relative frequencies for all classes in a frequency distribution should equal 1 (or 100% when expressed as a percentage). This is because relative frequency represents the proportion of the total count that each class contributes. Thus, when you add all the relative frequencies together, they account for the entire dataset. If the sum deviates from 1, it typically indicates an error in calculation or data entry.

To compare two-way frequencies in a relative frequency table, you first convert the counts in the table into relative frequencies by dividing each cell by the total number of observations. This allows you to express the frequencies as proportions, making it easier to compare different categories across the two variables. You can then analyze patterns, such as which combinations of categories are more or less common, by examining the relative frequencies rather than absolute counts. This approach helps highlight relationships and trends in the data.
It depends on the circumstances. It is not always important
Yes they doHere are some properties of relative frequency:(a) The relative frequency of each outcome is a number between 0 and 1.(b) The relative frequencies of all the outcomes add up to 1..
Yes.
Absolute frequencies are calculated by first identifying intervals based on your data and then identifying the number of values within your data set that lie within these interval. Relative frequencies divide the absolute frequencues by the number of values in the set. It is a good practice to provide the absolute frequencies, perhaps in a bar chart of relative frequencies as a number above each bar.
