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 can you get the mode of a grouped data if there are two classes that both have the highest frequency?
If there are more than one class intervals which have the same frequency (equally qualifying to be the mode class) then both of the classes will be the mode class. this is called bimodal. However to calculate the mode of grouped data use the following formula Mode = L + [ (F - F1) / { (F - F1) + (F - F2) } ] * h where L = Lower limit of the modal class F = Frequency of the modal class F1 = Frequency of the class immediately previous of modal class F2 = Frequency of the class immediate next of modal class h = Range of the modal class (higher limit - lower limit) this is what i found out after reading books and understanding them. Please correct me if i am wrong. Thanks, Salman Ahmad
Find the mode of this set of data?
It has no mode.
What do you mean by mode and what is the formula of mode?
The mode is the data value that occurs the most number of times. If there are two data values that occur the most, then you will have 2 modes and it is called bimodal. Three or more is called multimodal. For example, if you have a set of numbers - 1, 4, 3, 2, 6, 4, 8, 4, 7, 3, 5. The mode is 4 as it occurs the most number of times.
What is the unique mode?
When there is only one mode in a data set.
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).
How is a frequency distribution used?
it is used to find mean<median and mode of 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. :)))
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 are you looking for when you are finding the mode of a set of data?
The mode is the data point that occurs the most number of times; in addition the data could be bimodal (2 modes) or multimodal (3 or more modes).
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.
Mode of grouped of data?
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 the properties of mode?
The mode is a measure that appears most often in a set of observations. It can be used with qualitative data whereas the other traditional measures of "central tendency" cannot. Also, by its very definition, it must be a value that is observed. However, for grouped data, the mode is very dependent on the grouping values.
