Damn you are the best. I feel really bad for having negative views in the first few lectures, but now I don't think anyone can make statistics so interesting. Legend.

Rightmost word is used with both stem and leaf, is it a mistake or I understood wrong??
28:35
Stem and leaf diagram

[@amanabrahamx]

Stem is left

[@kartiksaxena4]

Stem contains everything except rightmost digit and leaf contains only rightmost digit

[@sayanghosh6996]

it is not a mistake, it is how english works.
She said stem has all BUT the rightmost digit, meaning all digits except the rightmost digit, and the leaf has just the rightmost digit.

Respected madam. At 19:56. No of students are 49 . Accordingly the number of students for the class 50-60 would be 17 and not 18.

[@rsupriya1229]

[@shrutimanmukherjee3605]

While constructing the frequency table, to which category would have '90' belonged if a student happened to score 90 marks?

[@sohanpattnaik4331]

if a student happens to score 90, then according to this video it will belong to a new class interval i.e. (90-100) and instead of 6 we would need 7 classes

[@satyabratachowdhury5026]

at 18:44
what if i choose the interval as 30-39, 40-49 , 50-59 , 60 - 69 , 70- 79 , 80-90
just as told in the lecture , no digit should appear in two classes .
and if i may ask - what should i do 80-89 , 90 ,,,, is it ok as 80 -90 ?

[@divakarang.k4054]

should be 30- 40, 41- 50

[@g0d_iz_gamer]

we make intervals that are sensible and useful to us no use leaving single value out of intervals so u should choose reasonable interval.

[@rishi4567]

if the marks of the students is not an example of continuous data then why do that have represented it in that way

[@nirvanj1580]

There are 49 students 🙁 18:00

Not necessarily. Colloquially we use kg for weight. You don't reply in Newtons when someone asks your weight
