16,649

volunteer
i see it
16,649
6
[]
volunteer
ok so there's a rule to rotating points 90 degrees counterclockwise
16,649
7
[]
volunteer
your new point would be at (-y, x), using the x and y coordinates from your original point
16,649
8
[]
volunteer
or in this case from point b
16,649
9
[]
volunteer
you can kind of picture the rotation like a circle
16,649

volunteer

Hi Alex! I am not very experienced in excel. What kind of help do you need?
16,667
1
[ { "pii_type": "PERSON", "surrogate": "Alex", "start": 3, "end": 7 } ]
volunteer
Or rather, what are you trying to do in Excel?
16,667

[]
student
Its stats related but nobody is taking my session at the moment
16,667
3
[]
student
Let me screenshot it
16,667
4
[]
volunteer
Maybe I can help
16,667
5
[]
student
Ok give me one sec
16,667
6
[]
volunteer
Okay! :)
16,667
7
[]
student
here it is
16,667
8
[]
student
so so far i did the A part already
16,667
9
[]
student
i wish i could screenshare but it wont show so we'll do this
16,667
10
[]
volunteer
So you want to click on the empty blue box next to mean, for example, and start typing =AVERAGE()
16,667
11
[]
student
yeah but for hat cell
16,667
12
[]
student
wait let me show you what i emailed my techer
16,667
13
[]
volunteer
Then, you'll type something like =AVERAGE(A2:A81)
16,667
14
[]
volunteer
but replact A2:A81 with the range of light bulb values
16,667
15
[]
volunteer
The row and column of the first data point and the last
16,667
16
[]
student
"There are 80 values, but A2:A80 is only 79 values. You are missing the bottom one. "
16,667
17
[]
volunteer
Is there a value in A81?
16,667
18
[]
student
The reason why I put A1:A80 is because A1 is the title of that section. "Sorted Lifetimes (hrs)
16,667
19
[]
volunteer
That's good! But if there's 80 values, then there should be an entry in A81
16,667
20
[]
student
so how do i do that
16,667
21
[]
student
bc then it'll count the title
16,667
22
[]
volunteer
Could you clarify if there is an entry in A81?
16,667
23
[]
student
A1 is sorted lifetime
16,667
24
[]
volunteer
Okay. Is the column Light Bulb Lifetimes (hrs) column A then?
16,667
25
[]
student
yes
16,667
26
[]
volunteer
Okay! In the box next to mean, we want to compute the average of the column
16,667
27
[]
volunteer
We can enter =AVERAGE(A2:A81)
16,667
28
[]
volunteer
Because the 80 values should be in A2 to A81
16,667
29
[]
student
Ok
16,667
30
[]
student
Ohh I do both
16,667
31
[]
volunteer
either column A or B should be fine
16,667
32
[]
student
Ohh I have to do it to Light Blumb (Lifetimes hrs)
16,667
33
[]
volunteer
because they are both the same data set, just sorted differently
16,667
34
[]
volunteer
However, you need to go up to row 81 to get all 80 values
16,667
35
[]
volunteer
since the data set starts at row 2 due to the title
16,667
36
[]
volunteer
That's what your teacher was talking about I believe :)
16,667
37
[]
student
Ok so type in for mean A1:A80
16,667
38
[]
volunteer
Not quite! We don't want to include A1, which is the title
16,667
39
[]
volunteer
We want the first 80 numeric values
16,667
40
[]
volunteer
which is A2:A81 :)
16,667
41
[]
student
Exactly thats why I did: A1:A80
16,667
42
[]
student
let me show you the cell
16,667
43
[]
volunteer
A2:A80 is the first 79 values
16,667
44
[]
volunteer
A80 is not the 80th value, just row 80
16,667
45
[]
volunteer
the 80th value is in row 81
16,667
46
[]
student
look
16,667
47
[]
student
theres no number in 81
16,667
48
[]
volunteer
Oh okay! That was probably a copy and paste error
16,667
49
[]
student
ok let me start over then on a new excel sheet from the original
16,667
50
[]
volunteer
Can you try redoing part A, making sure you copy all the values?
16,667
51
[]
student
fixed it
16,667
52
[]
student
i fixed it
16,667
53
[]
volunteer
Awesome!!
16,667
54
[]
student
so do
16,667
55
[]
student
=AVERAGE(A2:A81)
16,667
56
[]
volunteer
Yes!
16,667
57
[]
student
=MEDIAN(A2:A81)
16,667
58
[]
volunteer
Yep :)
16,667
59
[]
student
=MODE(A2:A81)
16,667
60
[]
student
uhh what do i do for midrange
16,667
61
[]
student
there's no formula
16,667
62
[]
volunteer
Can you add MIN(A2:A81) and MAX(A2:A81) and divide by 2?
16,667
63
[]
student
oh that's what i do?
16,667
64
[]
volunteer
Since column B is sorted
16,667
65
[]
volunteer
the low and high are at the top and bottom
16,667
66
[]
student
ok but how would that look formual wise
16,667
67
[]
volunteer
I believe Alex
16,667
68
[ { "pii_type": "PERSON", "surrogate": "Alex", "start": 10, "end": 14 } ]
student
oh its =(MAX(range) + MIN(range)) / 2
16,667
69
[]
student
mhm
16,667
70
[]
volunteer
That works too!
16,667
71
[]
student
Alex
16,667
72
[ { "pii_type": "PERSON", "surrogate": "Alex", "start": 0, "end": 4 } ]
student
=STDEV(A2:A81)
16,667
73
[]
volunteer
yep :)
16,667
74
[]
student
now i have to subtract
16,667
75
[]
volunteer
Yeah, just use the letter of the column and number of the row to specify the values you want to use in the equation
16,667
76
[]
student
how would i do that
16,667
77
[]
student
ok
16,667
78
[]
volunteer
It's gonna be similar to how we did things for midrange!
16,667
79
[]
student
Ok done
16,667
80
[]
volunteer
Nice! :)
16,667
81

16,667
87
