Welcome to this section.

In this section, we're going to now start creating some reports within the Power BI desktop.

We're going to be using the BI visualizations to be able to do this.

Now we're going to be working with three main visualizations in this section.

We're going to start off with the table visualization just so that we can see how Power BI easily summarizes

and aggregates your data.

Then we're going to move into your matrix and we're going to also use the card visualization.

What's going to be looking at different methods of aggregation.

So we're going to be seeing that we can change the method of aggregation by default.

We sum up our data, but we may want to know what is the average or what was the minimum value or the

maximum value.

How do we do a count?

We'll also see that there's other functions as well, such as distinct count, which can be really useful.

Then we're going to move into looking at how we use slices.

Now, if you've ever used Excel slices, you'll know that slices are used to filter your data.

So basically it's going to give the user a graphical control that they can select different options,

and then the other visualizations within the page will be filtered according to the selections that

have been selected.

So really powerful.

And we're also going to look then at how we can actually filter within a visualization.

So you're going to see that we've got visual level filters as well that we can apply.

So lots of powerful features that we've got just within the section alone.

But yet again, let's jump into the lessons and let's see how we do this.

I'll see you there.
