Measures of Dispersion (Grouped Data) | Basic Statistics

What if the given data is
1-5
6-10
11-15
16-20
21-25

Why is it the range still 25? Though I did the same process as yours.

Thank You Po dito sir napaka laking tulong po

[josephokoth]

thank you...when should i use N and N-1 im confused in finding variance

[rizmandesu]

for the variance, why are you using the formula for ungrouped data?

[unknown-bxmy]

why in my course the denominator of s2 is just n and in online explanationa is n-1

[alexixis]

Pano kung zero ano yung class boundaries?

[charmaeempig]

Very helpful, sana tagalog para madali magets

[emmanlovesart]

i thought the N is the number of values

[fridayusankurong]

i can't thank you enough sir. i have issues with confidence coefficient

Wrong yung range, it should be 21.5 - 12.5 which is 9
