# How to Talk to Your Kids about Quality Engineering, Part 2: Statistical Sampling

I really can’t make this stuff up.
I wrote a post a couple of years ago entitled: “[How to Talk to Your Kids about Six Sigma and Quality Improvement](https://blog.minitab.com/blog/adventures-in-software-development/how-to-talk-with-your-kidsabout-quality-improvement?hsLang=en),” in which I lamented about “Community Hero” day in my daughter’s 1st grade class and the need to explain to her why I wasn’t at the "community-hero-level" of Maggie’s Mommy, the pediatrician.
Well, now it's two years later and my son, Thomas, is in class with Maggie’s little brother, Sam. Seriously. *Again.* Instead of Community Hero Day, however, the classroom had Engineering Day. Step aside, Maggie’s Mommy!
*Or maybe not.* Enter Maggie and Sam’s Daddy, the aerospace engineer.
Seriously, this family.
After a fun-filled Engineering Day, Sam and Thomas were excitedly telling me about all the fun things they learned about. “You design things, you build things—YOU MAKE THINGS—IT’S SO AWESOME!” Every engineer dreams of the day when their child’s eyes light up at the thought of building things. Nothing, not even a trip to Disney World, tops the feeling of knowing you may have brought an engineer into this world. This was it. I did it. I proudly exclaimed “I’m an engineer!”
***And, then….***
Thomas: “Weeeeell, not really….”
Me: “No, I am”
Thomas: “Well….you really don’t make *things*…real *things*. You make software. That’s not REAL.”
Sam: “My daddy makes planes.”
Thomas: “See, Sam’s daddy is a REAL engineer.”
Me: “*I’m* a REAL engineer.”
My daughter, Emilia, came to my rescue: “Thomas, Mommy *was* a real engineer. Mommy, tell them about the old days when you were a real engineer.”
And. Breathe. This was not happening again. Software Quality Engineering is REAL and I intended to prove it.
When my kids bounced out of bed the next day, they did what is now second nature. They grabbed for, of course, their iPad. But it wasn’t there.
“Where’s my iPad?”
“Sorry, only REAL things today!”
“What?”
“But, what are we going to do?”
“Real things.”
I *really* had underestimated the joy that this would bring me.
And so, to prove to them that a majority of the “things” they do during the day rely on software, I introduced statistical sampling. We talked about pulling a [random sampling](https://blog.minitab.com/blog/statistics-and-quality-data-analysis/collecting-random-data-isnt-monkey-business?hsLang=en) of their toys to provide a picture of the entire population.
And so they headed to the toy room and did just that. Then we entered the data in the [statistical software](http://www.minitab.com/products/minitab) I help engineer. The results: 67.7% were either software or involved the use of software.
This was not the world I grew up in. I vaguely recall the rich kids having Pong back in the day, but, aside from that, nothing that needed software. Sticks, rocks and, if you didn’t cause trouble, a bike. Gangs of kids on Huffy bikes—that was my childhood.
So, our sample provided a picture and a couple of very good lessons:
1) Software Engineering is real. Very real.
*and*
2) My kids rely far too much on it.
As any respectable engineer would do, I adjusted based on the result. This holiday season, my children unwrapped chemistry sets, architect sets, books, and, because we can’t stop cold turkey, a *little* technology.
So, did they get their iPads and video games back? Of course. But not until I made them sit through several updates that we had been procrastinating.
And, did the long wait during the updates frustrate them and impact their user experience? Yep.
*Hmmm...if only there were people to do something about that.*
