Need Help with basic Stats

[SidewaysN2second]

hey guys, i just started the course, and i make the commute to university, anyway i am having to construct a time plot, by hand, but i just cannot understand the data, the question is #2 a + b of the link, can anyone figure it out and explain it to me?

the link http://www.umanitoba.ca/statistics/100/term2/a1.pdf

thanks everyone

Link doesn't work for me

it looks like a bunch of "instantaneous breathing rates" in "breaths per minute"... the first one is in the upper left, the last one is the in the lower right, 40 in total.

i know that, but i dont understand what the question is asking of me, im not too sure how to organise it

well histogram should be self expanatory...

i dunno what a time plot is, but i would guess it means to plot them in the sequence they happened... 1 through 40. since there are no other units of time...

could anyone draw a quick example on a piece of paper, scan it, and send it to me? i know its asing alot but i am super struggling here, i need a visual example, damn Profs.. i cant relate any of the examples i have here

uh... yea i don't have *that* much free time

but what i think you need to do is make a graph with the numbers 1 through 40 as the units on the x-axis... then the y-axis should be in units of breaths per minute. does that make sense?

ok, i think i got you, 1 to 40 up and down, and a suggestion on what i should use as the intervals for Breaths Per minuite on the bottom?

no no, the 1 to 40 should be on the x-axis (sideways). that is how i would imagine a time plot should be at least...

anyways, interval is up to you... i would do like 3 bpm or something.

does 1-40 have to be done like 1 2 3 4 5 6 7 etc... or can i do tht in intervals as well?

well i dunno what your prof's personal preference is, but i think intervals of 5 would be fine...

just to make sure, intervals refer to just the markings on the axis... each individual data point needs to be plotted however.

lol, where do i get a piece of paper with 40 lines!?
