Best Answer

The mode of a set of data is the most frequent value. Sometimes there is more than 1 most frequent value so there is more than one mode. For example our set is { 1,2,3,4,4,5,6,9} the mode is 4 and here is another set {1,2,3,3,4,5,6,6,7} the modes are 3 and 6 and we say the set is bimodal.

What is a 'crude mode'?

Crude Mode (Grouped data) is the midpoint of the class limit with the highest frequency. Therefore, in getting the Crude Mode, look for the highest frequency and look at it's class limit. Lastly, get he class limit's midpoint. The Class Limit's midpoint will be the Crude Mode (Grouped Data).

What is the mode of grouped data?

To calculate the mode.. Add the lower limit and upper liit of the class interval with the most frequency. :)))

How is a frequency distribution used?

it is used to find mean<median and mode of grouped data

Formula for finding mode in grouped data?

L + d1/d1+d2 x w

Can a grouped of data be grouped?

Not sure what a "grouped of data" means!

What type of graph would be needed for a mode calculation?

For discrete data, a bar chart. For continuous data a grouped frequency chart (histogram).

What does the word mode mean when measuring in rainfall?

The mode is the numerical value of rainfall (or range of values, if dealing with grouped data) that fell on the most periods.

How can you find mean median and mode for GROUPED data?

Mean, median and mode are ways to find averages. The mode is the most common answer in a set of data. The median the number that is in the middle when the numbers are put in order. The mean is the statical average.

How do you calculate the mode of grouped data if there are two classes with the same highest frequency?

Both classes are modal classes.

When does a set of numbers have no mode?

When data is grouped and each of the intervals or categories has the same relative frequency, then no mode can be calculated. This can happen when the dataset is very limited. If all numbers in a dataset are the same, then it is impossible to calculate a mode, no matter how the data is grouped. Sometimes the level of variation is so much less than our measurement capability that we can not detect variations in variables.

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 the categories by which data are grouped?

Data can be grouped or ungrouped. The categories data are grouped in depend on the data. For example, data collected about people could be grouped as male/female, by ages, or some other common characteristic. Data collected about dogs could be grouped by breed of dog, age, long hair/short hair, or size.
