In Math what is class frequency?
class frequency is the number of observations corresponding to a particular class.
What is a modal class interval?
It is the class interval with most number of observations.
How is the relative frequency for a class computed for qualitative data?
It is the number of times (frequency) that a value in the required class is observed divided by the total number of observations.
How do i determine the number of classes ie intervals estimate the frequency of the class with the least and greatest frequency and determine the class width on a histogram?
try sqrt(N) where N represents the number of observations you have...
In a frequency distribution what is the number of observation in a class called?

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.
What is a modal class interval?
It is the class interval with most number of observations.
How do you figure out the relative frequency with a class limit of 0-9?

How is the relative frequency for a class computed for qualitative data?
It is the number of times (frequency) that a value in the required class is observed divided by the total number of observations.
Why is class midpoint in statistical formulas important?
When data are summarised into classes, their exact values are lost. There is no way of knowing whether the original observations were near the bottom of the class, the top of the class or evenly spread out. Assuming that all the observations that fall into a particular class take the midpoint value is a reasonable approximation. It is the maximum likelihood unbiased estimate. It also sets the variance within each class to 0.

What is the difference between modal class height and modal height?
The modal height is the value of height which has the largest number of observations. The modal class height is the height for which the class has the greatest number. An example: Heights: 161, 163, 163, 171, 172, 173, 174 Modal height: 163 (2 observations, all others are unique). If the classes are 161-170, 171-180 then modal class height = 171-180 with 4 observations.
What is a number of pupils called?
class
What is the particular language of a particular group called?
The particular language of a particular group is called a dialect. Dialects can vary based on factors such as region, social class, or cultural background within a larger language group.
How do you get class interval?
You don't GET class intervals. The person analysing the data chooses what class interval gives the best summary of the data. Ideally you are looking for class intervals that havea reasonable number of observations in each class (5 or more),a reasonable number of classes,(sometimes) observations within the same class are as similar to one another as possible while observations between classes are as different as possible (maximum discrimination),a nice round numbers as their midpoints.The first three are important for some kinds of statistical analyses. The last is to make calculations simpler and interpretation of the results easier.
