Narrator: Welcome to the
2
00:00:00,000 --> 00:00:02,000
Numerical Tools Solution walkthrough.
3
00:00:02,000 --> 00:00:04,000
As a quick reminder,
4
00:00:04,000 --> 00:00:06,000
Ethan reached out because he needs you to help validate
5
00:00:06,000 --> 00:00:10,000
some high level stats about our products and customers.
6
00:00:10,000 --> 00:00:13,000
So in the Solution Preview,
7
00:00:13,000 --> 00:00:15,000
I've added in all of the answers in bold,
8
00:00:15,000 --> 00:00:17,000
but let's head over to Power BI
9
00:00:17,000 --> 00:00:19,000
and check these out for ourselves.
10
00:00:19,000 --> 00:00:21,000
All right, so our first question is,
11
00:00:21,000 --> 00:00:24,000
what is our average product cost, right?
12
00:00:24,000 --> 00:00:26,000
And so from the Product Lookup Table,
13
00:00:26,000 --> 00:00:30,000
we want to head over to our Product Cost column
14
00:00:32,000 --> 00:00:36,000
and Transform, Statistics, Average,
15
00:00:38,000 --> 00:00:43,000
and we get 413.66 if we round to two digits there.
16
00:00:44,000 --> 00:00:45,000
So that checks out.
17
00:00:46,000 --> 00:00:51,000
Up next, how many colors do we sell our products in?
18
00:00:51,000 --> 00:00:56,000
So we're gonna head over to our Product Color column,
19
00:00:56,000 --> 00:00:59,000
Transform, Statistics.
20
00:00:59,000 --> 00:01:00,000
And then again, here,
21
00:01:00,000 --> 00:01:03,000
we want to count the distinct values within this column,
22
00:01:03,000 --> 00:01:04,000
right?
23
00:01:04,000 --> 00:01:06,000
And we get 10, which again,
24
00:01:06,000 --> 00:01:08,000
that aligns with what we saw in the solution preview.
25
00:01:09,000 --> 00:01:13,000
Next, how many distinct customers do we have?
26
00:01:13,000 --> 00:01:15,000
So for this we're gonna head to the Customer Table.
27
00:01:16,000 --> 00:01:19,000
And our Customer Key column
28
00:01:19,000 --> 00:01:23,000
is going to give us the unique number of customers.
29
00:01:23,000 --> 00:01:28,000
So from here, Transform, Statistics.
30
00:01:28,000 --> 00:01:30,000
And then again, we're gonna count distinct.
31
00:01:31,000 --> 00:01:36,000
And we get 18,148, which looks good.
32
00:01:38,000 --> 00:01:40,000
And then our last question here
33
00:01:40,000 --> 00:01:43,000
is what is the maximum annual customer income?
34
00:01:43,000 --> 00:01:46,000
So we'll scroll over to our Customer Income field,
35
00:01:49,000 --> 00:01:53,000
and then we will use our maximum function here
36
00:01:53,000 --> 00:01:57,000
to get that value, and that is 170,000.
37
00:01:57,000 --> 00:01:57,000
Perfect.
38
00:01:57,000 --> 00:02:00,000
The last piece here was to return all of the tables
39
00:02:00,000 --> 00:02:02,000
to their original state.
40
00:02:02,000 --> 00:02:03,000
And with that,
41
00:02:03,000 --> 00:02:06,000
that's gonna wrap up this solution walkthrough
42
00:02:06,000 --> 00:02:07,000
on the numerical tools.
