Which type of graph would best display interval data?
A histogram
Interval and ratio data statistics?
Yes, they do exist.
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 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.
Is course evaluation scale nominal or ordinal or ratio or interval?
It is Ordinal:Order the data from smallest to largest or "worst" to "best".Each data value can be compared with another data value.
What type of graph is used for interval or ratio data?
It is a HISTOGRAM.
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 histograma?
Histograma is a Spanish of histogram. Histogram is a bar graph in which data are divided into equal intervals, with a bar for each interval. The height of each bar shows the number of data values in that interval.
Which type of graph would best display interval data?
A histogram
Is elevation interval data or ratio?

Would a histogram help you to data analyze data?
As a visual representation of data, then a histogram is a way of analysing data.
Is Age nominal interval or ordinal data?
Age is none of the items listed. Age is ratio data.
Is math score interval data?
No; since you refer to a math score (and not a math grade), it is ratio data.
What is the difference between interval data analysis and ratio data analysis?
Data comes in various sizes and shapes. Two of them are Interval and Ratio. Interval is a measurement where the difference between two values is meaningful and follows a linear scale. For example: in physics, temperature 0.0 on either F or C does not mean 'no temperature'; in biology, a pH of 0.0 does not mean 'no acidity'. Interval data is continuous data where differences are interpretable, ordered, and constant scale, but there is no 'natural' zero. Ratio is the relation in degree or number between two similar things or a relationship between two quantities, ordered, constant scale, with natural zero. Ratio data is interpretable. Ratio data has a natural zero. A good example is birth weight in kg. The distinctions between interval and ratio data are slight. Certain specialized statistics, such as a geometric mean and a coefficient of variation can only be applied to ratio data.
