Literally googling the terms would answer your questions.

Cumulative frequency is the running sum of frequencies. Ie 10,65,...

Part b tells you the scale to plot the CF.

The rest tells you how to do it.

oh

#

bro

#

listen

#

i found out

#

the ting bc someone helped me

#

idk how to plot the graph now

Plot the points of CF on the upper bound of the heights and draw the s curve

dim vortex Plot the points of CF on the upper bound of the heights and draw the s curve

english please ? 😭

#

@dim vortex

#

it suppose to look like this?

Ok, so if you look at the first height interval it is between 151-155. However because height is continuous we need the upper and lower bounds of the class. ie 150.5<=x<155.5 and the next class is 155.5<=x<160.5 etc. So by the time you get to 155.5 there is a point plotted at (155.5,10). And so on

#

so it'll be

#

155.5,10

#

165.5,85?

#

would be the next one? @dim vortex

#

uh @dim vortex

dim vortex Jun 21, 2023, 9:32 PM

#

(165.5,65)

#

(160.5,65) sorry

#

#

Here's an example

#

#

will this be the rest?

dim vortex Jun 21, 2023, 9:34 PM

#

Yes. Plot them points and connect the s shape from the origin to the last point
