📘 Chapter 6 – Excel Functions for Descriptive Statistics

Use these Excel functions to calculate common descriptive statistics from student-related datasets like grades, study hours, or survey responses.

Statistic Excel Function Example
Mean (Average) =AVERAGE(range) Average GPA of 5 students in A2:A6:
=AVERAGE(A2:A6)
Median =MEDIAN(range) Median study hours from B2:B10:
=MEDIAN(B2:B10)
Mode =MODE.SNGL(range) Most common quiz score in C2:C12:
=MODE.SNGL(C2:C12)
Standard Deviation (sample) =STDEV.S(range) Std dev of grades in D2:D20:
=STDEV.S(D2:D20)
Variance (sample) =VAR.S(range) Variance of test scores in E2:E20:
=VAR.S(E2:E20)
Range =MAX(range)-MIN(range) Range of weekly screen time:
=MAX(F2:F12)-MIN(F2:F12)
Minimum =MIN(range) Lowest midterm score:
=MIN(G2:G15)
Maximum =MAX(range) Highest final score:
=MAX(H2:H15)
Count =COUNT(range) Count how many students submitted homework:
=COUNT(I2:I30)
Quartile =QUARTILE.INC(range, quart) 1st quartile of project grades:
=QUARTILE.INC(J2:J25, 1)
Interquartile Range (IQR) =QUARTILE.INC(range,3)-QUARTILE.INC(range,1) IQR for student GPAs:
=QUARTILE.INC(K2:K20,3)-QUARTILE.INC(K2:K20,1)
Skewness =SKEW(range) Skewness of class attendance:
=SKEW(L2:L30)
Kurtosis =KURT(range) Kurtosis of pop quiz scores:
=KURT(M2:M30)
