They are both modal classes - the distribution is bi-modal.

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
What is grouping of data into classes giving the number of observation in each class?
frequency distribution
Suppose that a frequency histogram and a cumulative frequency histogram are constructed from the same set of data using the same classes is the frequency for each class is the frequency equal to the?
the frequency is less than OR EQUAL TO the cumulative frequency
Open ended class within the frequency distribution?
If, in a frequency distribution, the initial class interval is indeterminate at its beginning and/or the final class interval is indeterminate at its end, the distribution is said to possess "open ended" classes.
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...
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).

It is a grouped frequency table.

What is grouped frequency distribution?
If the observations are grouped together into classes, then the number of observations for each class gives the grouped frequency distribution (FD). This kind of FD is particularly important when the data are continuous so that you are likely to have very small frequencies for a very large number of values.
What is modal class in maths?
The class that has the highest frequency (number)
What is a sentence for class interval?
class interval - one of several convenient intervals into which the values of the variate of a frequency distribution may be grouped.
Of the spectral classes the highest temperature class is designated as what?
Class O
How many types are there of frequency distribution?
Introduction:Frequency distribution is used to compress and summarize the whole data by grouping the data into classes and records the data points that fall in each class. The frequency distribution is considered as the base for descriptive statistics and they are also used to define the ordinal, nominal and the interval data. Frequency distribution is the comfortable way of grouping and organizing the data.Example of Frequency Distribution:Consider the frequency table for the students in a class where the data has been grouped according to the height of the students. Range of height Total number of student's cumulative frequency3.0 - 4.5 feet 15 154.5 - 5.0 feet 20 355.0 - 6.5 feet 25 506.5 - 7.0 feet 30 80In the case of nominal data the use of the contingency table is required. The frequency distributions are used to present the data graphically.Types of Frequency Distributions:There are three types of frequency distributions. Cumulative frequency distribution,Grouped frequency distribution,Cumulative Grouped frequency distribution.Cumulative frequency distribution (type 1):The cumulative frequency can be found from the frequency distribution by adding the cumulative frequency column. The highest cumulative frequency should be equal to the total number of frequenciesTemperature Frequency Cumulative frequency47 3 2246 3 1945 4 1544 3 1243 3 9Grouped frequency distribution (type 2):The grouped frequency distribution can be formed by grouping the values together into the class intervals. The range can be calculated using the maximum and the minimum values.Data set for temperature45 48 47 43 4442 45 43 46 4645 47 46 47 4543 47 45 47 4644 43 44 46 47The grouped frequency distribution is given byClass interval midpoint frequency45- 47 46 1542 - 44 43 7Cumulative grouped frequency distribution (type 3):In cumulative frequency distribution the cumulative frequency column is added to the grouped frequency distribution so that we can get the cumulative grouped frequency distribution.Class interval midpoint frequency Cumulative frequency45- 47 46 15 2242 - 44 43 7 7
What is the frequency in a frequency table?
The frequency in a frequency table is the number of occurrences within each class width. The total frequency is the sum of all frequency's within all the classes.
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. :)))
