What is the difference between a frequency histogram and a relative frequency histogram?
Both divide the data into discrete groups or intervals. The frequency histogram gives the number of times the data occur in the particular group or interval, while the relative frequency histogram gives the fraction of times the data occur in the particular group or interval.
What is an interval on a relative frequency histogram?
I think the answer is class and... go ask the teacher or flunk
Each bar in a what indicates the frequency of a interval?
histogram
What kind of frequency distribution graph is appropriate for scores measured on an interval or ratio scale?
histogram
How can you tell when an interval of a histogram has a frequency of zero?
When sum of all counts is equal to the population size.

What is the mode of grouped and ungrouped data?
If you have calculated a histogram of your data, the mode is the interval with the highest relative frequency. If you have not created a histogram, and your dataset contains finite numbers (fixed decimal numbers), with some numbers repeating, then those numbers that repeat the most would be the mode. Otherwise, if you do not group your data, where you select an interval to calculate relative frequency, then a mode is not identifiable.
What is the name for a relative frequency distribution shown by heights?
Are you talking about a histogram of the relative frequency distribution.
How can you tell when an interval of a histogram has a frequency of zero?
When sum of all counts is equal to the population size.

What do you mean by histogram?
A histogram is a chart comprising bars but, unlike an ordinary bar chart, the widths (intervals) of the bars are different and their heights represent the frequency densities, not frequencies.
What is mean of term of frequency density?
Frequency density refers to the number of data points within a certain interval or range in a dataset. It is calculated by dividing the frequency of data points in a particular interval by the width of that interval. This measure helps to visualize and compare the distribution of data in a histogram or frequency distribution chart.
What type of graph displays data from a frequency table and has one bar for each interval of the table that contains values?
histogram
What is the relative frequency of an interval and how is it calculated?
The relative frequency of an interval is the proportion of observations that fall within that specific interval compared to the total number of observations in the dataset. It is calculated by dividing the frequency (the number of observations in the interval) by the total number of observations. This value is often expressed as a percentage to provide a clearer understanding of how common that interval is within the dataset.
How are histograms and bar graphs different?
In a bar graph, the height of the bars is relative to the frequency. In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"
