In ungrouped data with n=12, where does the median (Q2) lie?

At the 6th value

Between the 6th and 7th values

Between the 5th and 6th values

For ungrouped data with n=20, Q1 position using (n+1)/4 lies between which ranks?

6th and 7th values

4th and 5th values

5th and 6th values

What is the common formula for Q3 in grouped data?

Q3 = L + ((0.75N - cf)/f) × h

Q3 = L + ((N - cf)/f) × h

Q3 = L + (0.75N - cf) × h

What is the main difference when computing quartiles for grouped vs ungrouped data?

Grouped ignores cum. frequencies

Grouped uses interpolation within a class

Grouped uses whole numbers only

Ungrouped data {2,4,6,8,10}. What is Q2?

With L=10, N=200, cf=40, f=20, h=5, find Q1 using (0.25N).

12.5

14.0

11.0

Quartiles split data into how many equal parts?

Four

Two

Three

Which method places Q1 at (n+1)/4 for ungrouped data?

Using (n+1)/4 position

Using 0.25n without adjustment

Using n/4 position

For grouped data: L=100, N=400, cf=180, f=60, h=4. Compute Q3.

112

104

108

Q3 is the 75th percentile of the data, true or false?

False

Depends on data type

True

You can integrate the game into an LMS compatible with LTI 1.1 or LTI 1.3 such as Canvas, Moodle, or Blackboard. This way, the scores will be automatically saved into the platform’s gradebook.
