To calculate the midpoint of a class interval, we need to consider the upper and lower boundaries of the class. In this case, the lower boundary is 25 and the upper boundary is 30.
To find the midpoint, we add the lower and upper boundaries together and divide by 2. So, the calculation would be (25 + 30) / 2 = 55 / 2 = 27.5. Therefore, the midpoint of the 25 up to 30 class is 27.5.
Let me explain this in more detail. When we talk about class intervals, we are referring to a range of values. In statistics or data analysis, class intervals are used to group data into meaningful categories or bins. Each class interval has a lower boundary and an upper boundary.
In this case, the lower boundary for the class interval is 25 and the upper boundary is 30. The lower boundary represents the lowest value that falls into the class, while the upper boundary represents the highest value that falls into the class.
To find the midpoint of the class interval, we need to calculate the average of the lower and upper boundaries. This is done by adding the lower and upper boundaries together and dividing by 2.
So, in our case, we add 25 and 30 together, which gives us 55. Then, we divide 55 by 2, resulting in 27.5. Therefore, the midpoint of the class interval from 25 up to 30 is 27.5.
It’s important to note that the midpoint represents the average or central value of the class interval. It can be useful in data analysis to summarize or represent the data within that particular range. The midpoint can also help in making comparisons or calculations involving the class interval.
The midpoint of the class interval from 25 up to 30 is 27.5. This value is obtained by adding the lower and upper boundaries together and dividing by 2. Understanding the concept of class intervals and midpoints is crucial in statistics and data analysis as it allows us to organize and analyze data effectively.
