What is the meaning of lower class boundary in statistics?
In statistics the class boundaries are numbers that separate classes without forming gaps. To find the lower, you subtract 0.5 and to find the upper, you add 0.5. If the class is 3-7 the lower class boundary would be 2.5 and the upper 7.5. The upper boundary of one class will equal the lower boundary of the next class.
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.

weh? di nga? xD
What is the difference between class limit and class boundary?
Let's say you're measuring a continuous variable such as height or speed. You collect tally charts with classes 30 - 39, 40 - 49, 50 - 59 etc. 49 would be an upper class limit, but 49.5 would be an upper class boundary, since a reading of 49.4 for example falls outside the class limits.
How do you calculate the class boundary of the first class in statistics?
To calculate the class boundary of the first class in statistics, subtract 0.5 from the lower class limit of the first class and add 0.5 to the upper class limit of the first class. This is done to account for the fact that class boundaries fall halfway between the class limits.
What is class width?
Class width, from statistics, is the difference between the two boundaries of a class. A class is an interval that includes all of the values in a (quantitative) data set that fall within two numbers, the lower and upper limits of the class. Finally, a class boundary is the midpoint of the upper limit of one class and the lower limit of the next 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)
Is the boundary between the crust and upper mantle?
The boundary between the crust and the upper mantle is called the Mohorovičić discontinuity, commonly known as the Moho.
What is the difference between class limits and class boundaries?
Let's say you're measuring a continuous variable such as height or speed. You collect tally charts with classes 30 - 39, 40 - 49, 50 - 59 etc. 49 would be an upper class limit, but 49.5 would be an upper class boundary, since a reading of 49.4 for example falls outside the class limits.
What does your cumulative frequency graph tell you?
Cumulative frequency graphs or ogives are used to visually represent how many values are below a certain upper class boundary.
What is higher then upper midle class?
Upper class.
What are some social classes?
low class, middle class, upper class/high class
