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 the difference between a bar chart and a frequency table?
A bar chart is a graphical representation of data. A frequency table is a table of numbers, which breaks numbers into various groups, based on how often values occurs within ranges.
What is a frequency table interval?
equal groups on the table which is the scale
What is Mean from grouped frequency?
The victim should stay in groups.
Why would relative frequency be better than frequency while comparing two different groups?
you are aw some * * * * * Sadly you are not since you can't even spell the word. Relative frequency would be better because the two groups may be of different size.
What is a grouped frequency table?
A grouped frequency table is a statistic method to organize and simplify a large set of data in to smaller groups.
Who is most at risk for Rett syndrome?

What kind of table is one way to organize data into categories or groups?
A Frequency Table
What is the significance of the carbonyl IR stretch in determining the functional groups present in a compound?
The carbonyl IR stretch is significant in determining functional groups because it provides a specific signal that indicates the presence of carbonyl groups, such as aldehydes, ketones, carboxylic acids, and esters. By analyzing the frequency and intensity of this stretch in the infrared spectrum of a compound, chemists can identify and differentiate between these functional groups.
What is a advantage of using groups in frequency tables?
it is simple. the grouped frqency table allows you to analyze, organize and distibute your data in a very easy way. the GFT also allows you to enter groups. Ex: different age groups (50-60), (60-70) etc... in conclusion this helps you and your data. as for the normal frequency table, you cannot use age groups and it is not that organised
What is a double broken line graph?
They are used for when each data group contains two different sets of frequency data. A double bar graph is used to compare both between and within data groups
What are the three main age groups having the highest frequency of testicular cancer?
