Excel Data Analysis For Dummies, 2nd Edition

bold-faced description of what the step entails. Underneath that bold-faced

step description, I provide detailed information about what happens after

you perform that action. Sometimes I also offer help with the mechanics of

the step, like this:

1. Press Enter.

Find the key that’s labeled Enter. Extend your index finger so that it rests

ever so gently on the Enter key. Then, in one sure, fluid motion, press

the key by using your index finger. Then release the key.

Okay, that’s kind of an extreme example. I never actually go into that much

detail. My editor won’t let me. But you get the idea. If you know how to press

Enter, you can just do that and not read further. If you need help—say with

the finger-depression part or the finding-the-right-key part—you can read

the nitty-gritty details.

You can also skip the paragraphs flagged with the Technical Stuff icon. These

icons flag information that’s sort of tangential, sort of esoteric, or sort of

questionable in value...at least for the average reader. If you’re really inter-

ested in digging into the meat of the subject being discussed, go ahead and

read ’em. If you’re really just trying to get through your work so that you can

get home and watch TV with your kids, skip ’em.

I might as well also say that you don’t have to read the information provided

in the paragraphs marked with a Tip icon, either. I assume that you want to

know an easier way to do something. But if you like to do things the hard way

because that improves your character and makes you tougher, go ahead and

skip the Tip icons.

What You Shouldn’t Ignore (Unless

You’re a Masochist)

By the way, don’t skip the Warning icons. They’re the text flagged with a

picture of a 19th century bomb. They describe some things that you really

shouldn’t do.

Out of respect for you, I don’t put stuff in these paragraphs such as, “Don’t

smoke.” I figure that you’re an adult. You get to make your own lifestyle

decisions.

I reserve these warnings for more urgent and immediate dangers—things

that you can but shouldn’t do. For example: “Don’t smoke while filling your

car with gasoline.”

Excel Data Analysis For Dummies, 2nd Edition

I don’t think that these tools are going to be of interest to most readers of this

book. But if you already know how to do all the basic stuff and you have some

good statistical and quantitative methods, training, or experience, you ought

to peruse these chapters. Some really useful whistles and bells are available to

advanced users of Excel. And it would be a shame if you didn’t at least know

what they are and the basic steps that you need to take to use them.

Part IV: The Part ofTens

In my mind, perhaps the most clever element that Dan Gookin, the author of

the original and first For Dummies book, DOS For Dummies, came up with is

the part with chapters that just list information in David Letterman-ish fashion.

These chapters let us authors list useful tidbits, tips, and factoids for you.

Excel Data Analysis For Dummies, Second Edition includes three such chap-

ters. In the first, I provide some basic facts most everybody should know

about statistics and statistical analysis. In the second, I suggest ten tips for

successfully and effectively analyzing data in Excel. Finally, in the third chap-

ter, I try to make some useful suggestions about how you can visually analyze

information and visually present data analysis results.

The Part of Tens chapters aren’t technical. They aren’t complicated. They’re

very basic. You should be able to skim the information provided in these

chapters and come away with at least a few nuggets of useful information.

The appendix contains a handy glossary of terms you should understand

when working with data in general and Excel specifically. From kurtosis to his-

tograms, these sometimes baffling terms are defined here.

Icons Used inThis Book

Like other For Dummies books, this book uses icons, or little margin pictures,

to flag things that don’t quite fit into the flow of the chapter discussion. Here

are the icons that I use:

Technical Stuff: This icon points out some dirty technical details that you

might want to skip.

Tip: This icon points out a shortcut to make your life easier or more fulfilling.
