What is an 'ungrouped frequency table'?
A frequency distribution of numerical data where the raw data is not grouped.
Why you should use a grouped frequency distribution table instead of a regular table?
Because in case grouped frequency distribution table we are sending all i.e mixed frequencies at a time with diff bandwidth wheras in case of regular table we are sending each signal at a time.
What is the length of an interval in a grouped frequency table?
The length can be found by taking the larger number in the frequency group and subtracting it to find the range.
How do you find the average on a frequency table?
* To find the mean (or average) of a standard frequency table, you must firstly cross-multiply the frequncies with the independent variable in the left column. * Then, add up these products and divide by the total number of frequencies. * For grouped frequency tables, you must find a mid-point, a half-way value in each group, before cross-multiplying.
What are the parts of a frequency distribution table?
In a frequency distribution table, there are usually five parts/columns (12th grade statistics):class, frequency, mid-point, relative frequency, and cumulative frequency.

What information is available about the data in a regular frequency distribution table that is not available in a grouped table?
A regular fequency table reports the exact frequency for each category on the scale of measurement. However, when the categories are grouped together into class intervals, the table only reports only overall frequency for the interval but will not show how many scores are in each of the individual categories.

The length can be found by taking the larger number in the frequency group and subtracting it to find the range.
What is A grouping of data into classes giving the number of observations in each class is called a(an)?
It is a grouped frequency table.
If a sample of n 15 scores has been organized in a grouped frequency distribution table it is possible to obtain a list of all 15 scores from the table?
true

Under what circumstances should you use a grouped frequency distribution instead of a regular frequency distibution?
You should use a grouped frequency when you have a wide range of scores.
What is the difference between frequency distribution and relative frequency distribution?
Frequency distribution refers to a set of frequencies with a particular set of values into which a statistical population is grouped. Relative frequency refers to data presented in a table that demonstrates the relative frequency of multiple non-overlapping classes.
What is a frequency table?
A frequency table is a way of tabulating data, where the independent variable (that is, what you are measuring, such as height or length) is listed in the left hand column. The frequency, which is the number of times the independent variable occurs, goes on the right hand column. Sometimes, we represent the frequency by means of tally marks. A grouped frequency table groups the independent variable into "classes": e.g. 0 - 5, 6 - 10, 11 - 15...
