All language subtitles for 4Topic 2-1 Excel Data Types Week 1 Getting to Know Excel & Ente

so we just read about the different data types

that we're going to be using in this course in Excel

remember that

we're going to be using labels or text

as one data type

values or numbers as another data type

and we're also going to be taking advantage of excels

ability to do calculations for us

and we do that using formulas or equations

and a great

way to understand these different data types

is to use a real world example

on something that will be working on

which is what I have shown here in this chart

one of our first projects

is going to be working with local weather data

for wherever you happen to live

this is data for where I happen to live

in North Carolina

and the United States

and we're gonna be making plots

of how the weather changes throughout the year

and so we can look at this chart

and we can see those changes

but what we should focus on right now

is we should focus on the different kinds of data

that are included in making a chart like this

and here we can easily see two kinds

first of all

we're looking across all the months of the year

and we know that words

months are going to be a kind of text or label data

and so we have to have the ability to handle

text data like that

so that we can properly label our months clearly

we also have numerical values

because we have numbers representing

the temperature in each month

and so that's our value data

or our numerical data

that we're working with

we also have other kinds of label

or text data

where we need to be able to label

which temperature we're talking about

maybe it's the mean daily high temperature

or the mean daily low temperature

so this different kind of label

or text data

is something that we'll be working with as well

and so now we're going to see

how we input and handle this kind of data in Excel

in an Excel spreadsheet

so that we can make a chart like this in the future

so here we are in Excel

so we can see how these different data types work

when we're inputting data into Excel

so that ultimately

we can analyze data and produce plots

like the chart that I just showed you

you'll see immediately

that I've already entered in some text data

or label data

and these are labels for our data

we know that we're going to be working with months

and of course

that's a label itself

and we know that we're going to be working with

the mean daily high temperature

and the mean daily low temperature

and so these are called column headers

which is a form of text data

or label data

frequently for column headers

I like to bold everything

and so I'll just hit control B to bold

or we can also click on the B icon

to bold those text as well

and so that can bold and unfold

just like that

this is one piece of information

about setting up spreadsheets

but soon we'll have a separate topic

that goes into a little more detail

about the general principles we should use

when we're setting up spreadsheets

something else you'll notice in this

happens a lot

when we're entering

label or text data

is we can't fit all of that label

into a single cell

there's overlap there

gets cut off

we can adjust that

and excel very easily

if we hover over between the two

columns that were interested in adjusting

we can drag

and change that width

or the easy thing that I like to do

is we can double click

and it will auto correct

it'll auto fit that column with

for the text

so I just did that

for a mean daily high temperature in column B

and we'll do it for a mean

daily low temperature in column C

as well so now

we have our labels all set

and we'll just do a quick example here

we know that one of our months

our first month

is going to be January

and if I recall

collect correctly

the mean daily high temperature

for January

in my part of the world

is about 51 degrees Fahrenheit

the mean daily low is about

30 degrees Fahrenheit

so here we are

with our first

observation

and we have two different data types in here

we have a label or text

for the month

and we have

values or numbers

for our high

and low daily

mean temperatures

you can see

immediately

that Excel tells us

we're dealing with different information

because we have numbers

justified or aligned

on the right

and text justified or aligned

on the left

this is useful information

that we're going to be using later

so that we can know how Excel is interpreting

the data they're putting in

so we have two of our three data types here

let's do a quick example

so we can look at our third data type

which is a formula

or an equation

so I'm just gonna create a new column here

and I'm gonna call it difference

and what this will be is

we're calculating

the difference between

the mean daily high temperature

and the mean daily low temperature

we could do this by hand

we can do it on our heads probably

but the whole point of this course

is getting to the point

where we can get Excel to do this work for us

so we're going to use an

equation or formula

whenever we're asking Excel to do a calculation for us

we're going to tell Excel that

by starting our data

with an equal sign

now this is not going to be text data

it's not going to be a value

it's going to be

an equation or formula

and what we're going to do is

we're going to take advantage of cell referencing

and we're going to

say Excel we want

to take the value 51

and subtract

30 from it and so

you can see

our cell references

right in here

and you can see

that Excel is color coding

to tell us that it's going to subtract 30 in red

from 51 in blue

up in our equation bar

or formula bar

we have a version of that

equation as well

and if we hit enter

we'll get the result

and so we have

a data type

in our formula bar

of an equation or formula

but it is producing

numerical data for us

so few things we've seen in this video is

we've seen already

that we're using our cell referencing information

so that we can start to build equations

like we have here

and we've seen the power of the three different kinds

of data types

where we can put these all together

to keep our data organized

do calculations on it

and get it ready for plotting

so this is just a very simple example to make sure

that we're ready to start working with data in Excel

which is what we're going to be doing very soon
