Question
Q 16 ) Mention the excel formulas used to find frequency distribution of the weekly_self_study_hours Of first 100 students. a) b) c) d) —Court(Al :AI 00) —Courtifl Al 00) -Sumif (AI•AIOO) None of these.
Solution
The correct answer is:
a) COUNTIF(A1:A100)
The COUNTIF function in Excel is used to count cells that meet a single criterion. In this case, it would be used to count the frequency of each unique value in the range A1:A100, which represents the weekly_self_study_hours of the first 100 students.
Here's how you would use it:
-
First, you would need to identify all the unique values in the range A1:A100. You could do this manually, or you could use a formula like =UNIQUE(A1:A100) if you have a newer version of Excel that supports this function.
-
Next, you would use the COUNTIF function to count the frequency of each unique value. The formula would look something like this: =COUNTIF(A1:A100, [unique value]), where [unique value] is each unique value you identified in step 1.
-
You would repeat step 2 for each unique value.
Please note that this process would give you the frequency distribution for the raw data. If you wanted to create bins (for example, to group the students into categories like "0-5 hours", "6-10 hours", etc.), you would need to use a different approach.
