How do you find mid point when class interval and ffrequency is given?
To find the midpoint of a class interval, you add the lower limit and the upper limit of the interval and then divide the sum by 2. For example, if the class interval is 10-20, the midpoint would be (10 + 20) / 2 = 15. This midpoint can then be used in calculations like finding the mean or in statistical analysis involving frequency distributions.

Why do you use assumption that mid point repeats frequency times in a data?
The assumption that the midpoint of a class interval represents the frequency of that interval is used to simplify calculations in statistical analysis, particularly in constructing histograms or calculating measures like the mean. This approach allows for a more straightforward estimation of the central tendency of grouped data, as it provides a single representative value for each interval. By using the midpoint, we can approximate the overall distribution while acknowledging that actual data points within the interval may vary. This method balances accuracy and practicality when dealing with large datasets.
What are the three interval choices when you form a squad?
When forming a squad, the three interval choices typically refer to the selection of players based on specific time frames or performance metrics. These intervals might include short-term performance (recent games), mid-term performance (over a season), and long-term performance (career statistics). Each interval provides a different perspective on player capabilities and consistency, helping to inform strategic decisions in team composition.
What is the mid point of a frequency?
The midpoint of a frequency distribution is the value that divides the distribution into two equal parts. It is calculated by adding the lower and upper limits of a class interval and dividing the sum by 2.

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.

Why the median changes by changing the size of class intervals in frequency ditribution?
Because median is the mid of the class intervals. Therefore, it is a positional measurement. Hence, if the size of class interval increases or decreases then the middle position will also increase or decrease and thus median.
HOW DO YOU calculate mean mark by taking mid interval values?

How do you calculate mean for open end class interval?
In case of open end classes, mean can be calculated only if their class marks (Mid-Points) are determined. If such classes contain a large proportion of the values, then the mean may be subjected to substantial error.
What is the logic for binary search in masm 8086 program?
Take the mid value of the no. of inputs. If the key is greater than the mid value then add the mid value and the last value; then divide by two. Again check the middle value for the key and keep repeating this until you find the key. If key is smaller than the mid value. Add the first value to the mid value and divide by two. You will find the new mid value to compare and check for the key. Loop it until you get the key location.

What is the mode and median?
Both median and mode are the statistics formulas, Median is called mid value of the given data and mode is the value which occure repetedly in the given data.
What is mid level design?
Mid level design is related to class diagrams. It is usually static.
