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 are the components used in the frequency distribution?
class limit. class boundary. class mark. class widh.
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
How do you work out the class boundaries?
To calculate class boundaries, add 0.5 to the lower class limit and subtract 0.5 from the upper class limit of each class interval in a frequency distribution. This creates a buffer zone between the classes to avoid overlap when graphing or analyzing 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 is the sum of the product of the frequencies and the square of the class marks (ΣfX²60,55,40,48,52,36,50?
Step 1: Find the midpoint of each interval. Step 2: Multiply the frequency of each interval by its mid-point. Step 3: Get the sum of all the frequencies (f) and the sum of all the fx. Divide 'sum of fx' by 'sum of f ' to get the mean. Determine the class boundaries by subtracting 0.5 from the lower class limit and by adding 0.5 to the upper class limit. Draw a tally mark next to each class for each value that is contained within that class. Count the tally marks to determine the frequency of each class. What is this? The class interval is the difference between the upper class limit and the lower class limit. For example, the size of the class interval for the first class is 30 – 21 = 9. Similarly, the size of the class interval for the second class is 40 – 31 = 9.
Which EM waves has the highest frequency?
There is no upper limit to how much energy (and frequency) an electromagnetic wave can have. The highest frequency waves are called gamma radiation.There is no upper limit to how much energy (and frequency) an electromagnetic wave can have.

What is signal bandwidth?
Every line has an upper limit and a lower limit on the frequency of signals it can carry. This limited range is called the bandwidth. The signals ranging within the upper limit & lower limit are called bandwidth signals.
What is class boundary in statistics?
class boundary is the midpoint between the upper class limit of a class and the lower limit class of the next class sequence when making a class interval starting at the lowest lower limit in the bottom of a table.
In which class either lower limit or upper limit is missing?
open end class
How do you calculate class boundary?
Class boundaries are defined as the average of the upper limit of one class and the lower limit of the next class.For example:No. of runs (class)0-45-1010-1515-20and No. of batters (frequency)39104So the upper class boundary for the first class is the average of 4 (upper limit of class 0-4) and 5 (lower limit of next class 5-10), i.e. 4.5.Similarly, the next boundaries are 10.5, 15.5 and 20.5.In this way, there's no gap between 2 bars of a histogram, i.e., in this example the bars range from:0-4.54.5-10.510.5-15.515.5-20.5(Hope this helps! Took me a while to understand this stuff too :D)
How do you reduce frequency in speakers?
Using a crossover, you can limit the frequency response of the signal sent to speakers.
