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 are some methods of collecting data about local climate?
dew point relative humidity temperature all of the above
What makes a good chart in Excel?
A good chart is one that displays the information to present a picture that accurately reflects the relationship of each data item relative to the whole data set.
Would it be advantageous to group the data before constructing a frequency distribution?
The answer depends on the nature of the data and the domain. If the domain is continuous or very large relative to the number of observations, then it is very advantageous.
Why is a circle graph better?
That depends on the data you're trying to graph. Generally, circle graphs / pie charts / whatever you want to call them are good because they show pieces of data in proportion to the sum of all the data; that is, they illustrate the relative size of the pieces of data when compared to each other and compared to the whole.
When should relative frequencies be used when comparing two data sets?
When comparing large data sets.
What is mass of gold if relative density equals 19.3?
Insufficient data.
What is a shaded bar that provides a visual cue about the value of a cell relative to other cells?
A shaded bar that provides a visual cue about the value of a cell relative to other cells is called a data bar. It is commonly used in data visualization to quickly convey the magnitude of a data point in comparison to others in the same dataset.
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.
Does the coefficient of variation measure variability in a data set relative to the size of the arithmetic mean?
Yes.
What do the different sections or wedges show on a pie chart?
Each wedge shows the relative size of a specific data item when compared to the whole data set.
Why are graphs important to scientific research?
Graphs show a visual quntification of scientific data. They allow one to see changes and relative elements of the data being plotted.
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.

Why is selection of suitable transmission medium important in data transmission?
It will determine the speed, reliability and relative security of the transmission.
How do you Speed Up Response Time through data Archiving?
Database archiving is a proven strategy that will archive rarely used data and provide easy access to data on demand. Basically, data is most valuable when it is created. As data ages, its relative value comes down. Such data can be archived to improve real time transactions.
What is the difference between a histogram and a pareto chart?
Both graphs are used to summarize data. Pareto chart is used to establish differences between different groups of data and will assign relative importance to the different groups of data. Histogram is a data distribution graph that will determine if the particular set of data is symmetric or not.
