Statistics

For those of you wondering, “What exactly is it that Steve does in that Statistics class?”  Wonder no more.  We are dealing with things like “confidence intervals,” “measures of central tendency,” and “statistical inference.”    I am dealing with equations such as:

SEM

 

and

Standard Deviation Equation

 

 

And the sad thing is that, after two weeks of class, I’m really starting to understand what these things mean.  I’m reading the textbook. I’m doing the homework.  But the thing that has been the most help is a book called, “Even You Can Learn Statistics: A Guide for Everyone Who Has Ever Been Afraid of Statistics” by David Levine and David Stephan.  I got it for free from Amazon.com when they were having a sale, but it costs $12.55 now ($8.79 for the Kindle edition).  If you need Stats in the future (or now), I highly recommend it.

New Car

It's blue.

It’s blue.

Tuesday night I bought a car.  It is a 1999 Saturn SL sedan. It has 184K miles, and I bought it for cheap.  That’s a good thing, since I don’t have a lot of money.  I was told it gets 38mpg, but I have yet to test that.  If the mileage is that good, then I will be saving $100 per month in gas (after the cost of insurance is deducted from my gas savings). It has power locks (I use the power of my finger to lock it), power windows (I use the power of my arm to crank it up and down), and power steering (again with the arm power to wrench the wheel in circles as I turn).  Seriously though, have you heard of a car that’s “loaded”?  This car is the opposite of that.  It has no cruise control, no power seat, no power anything, really. I am thankful that the original purchaser (from whom I bought the car) paid the extra money for the air conditioning (which I have not tested yet, it being 15 degrees outside).

What DOES the car have?  It has four wheels, a motor that has been maintained very well, good brakes, etc.  In other words, everything I need to get from point A to point B.  My only true complaint about the car was the radio.  It had an aftermarket JVC CD player that skipped horribly when I tried to use it.  And so, right after buying the car I started looking at car stereos.

I found a car stereo at Best Buy that I wanted, and it seemed like the best one for me.  I looked it up on Amazon.com, and they had it for $25 less, so Best Buy did their price match and I walked out of the store with it this morning.   Before I walked out, the salesman told me I would need a $20 kit, a $20 connector, a $20 something else and installation costs $60.  When I told them I would be installing it myself, they just looked at me like I was from Mars.

Like this.

Like this.

So I bought my Pioneer DEH-X6500BT receiver and went home.  I watched a youtube video on how to take my console apart to get to the stereo, and followed their directions.  I removed the old stereo (which wasn’t working properly), and got the new stereo ready to install.  Then I looked at the mass of wires and, for the first time, wondered if maybe it would be worth it to have the Best Buy guys install it for $120.   But then I decided to return to the source of all knowledge: the internet.

Stereo wires

I found the above picture that showed me exactly which wires I should connect to which other wires, and I did so.  Then I put the new radio in place, and installed the microphone (so I can make hands-free phone calls).  Then the testing phase began, and I found that all the functions worked right, so I must have connected the wires correctly.  Now that I’m done and everything works, I’m happy I didn’t spend $120 to have the guys at Best Buy install it.

As a guy, it seems funny that I just got a new electronic device, installed it, and now I’m not using it (because I’m inside). I guess there will be enough time for that as I drive to work, drive to school, etc.

I figure the extra money I spent on this stereo (the non-phone version was $30 cheaper) will be worth it, since this microphone is way better than the one on my $20 earbuds (which only last a year).  Plus, if this car doesn’t last very long, I WILL be removing this stereo and installing it in my next car.

It has a USB port that I can use to charge my iPhone. It can play my music right off my iPhone (with my iPhone music library as well as Pandora). It has Bluetooth connectivity so that I can use the phone hands-free (which I have only tested with Kim so far, but it worked great).  It also has an “aux” port for whatever thing you want to connect to it that doesn’t use USB (like a cassette player).  The colors on the faceplate change every five or ten seconds (from blue to purple, red, pink, yellow, green, etc).  I am pretty satisfied with it.  All I need now is to figure out how to get it to do my laundry. 😉

Contentment

Sometimes it is easy to focus on the things we don’t have instead of focusing on the things we do have.  I have a faithful, godly wife who loves me. I have three healthy, mostly-well-behaved children who (by their own reports) are trusting in Christ for salvation. I have a roof over my head, food on the table, and a job where I can work to provide for my family. I have a God who loves me and has a plan for my life.

When we look at the people around us, it is easy to focus on their blessings without seeing their trials.  I know people who take lavish vacations, but deal with daily health problems I don’t want. I know people who live in places I want to live and drive cars I would like to drive who have unfaithful spouses, prodigal children, and other issues.  When the green-eyed monster rears his ugly head, I remind myself that everything comes with a cost.  As Robert Heinlein said, “TANSTAAFL.”  That stands for “there ain’t no such thing as a free lunch.” I COULD have a nice car to drive, but my children wouldn’t get the education I am paying for. I COULD go on a cruise with my wife, but I choose to pay the mortgage instead. When I examine my life in comparison to the other seven billion people on earth, I am truly blessed.

When I think about all the things God has given me, I would list the salvation of my soul as #1, because there isn’t a thing I own or a relationship I have that is more important than that.  There isn’t a person I know that I wouldn’t give up knowing if I had to in order to still be saved. There isn’t one single possession that I wouldn’t give away if I had to in order to keep my salvation.  God does not require a single possession from me to save me.  I don’t need to cut off ties with anybody in order to trust Christ.  But somehow knowing this keeps my priorities in line.

What’s the most important thing in my life?  It’s my relationship with God.  If something bad happened to one of my children, my wife, or my parents, it would not mean I lost my salvation. If I lost my job, my car, my house, my food, my sight, my hearing, my legs, or even my mind, I am secure in the belief that I cannot lose my salvation.

Someone once told me that the definition of contentment is “wanting what you already have.”  This is not an easy target to hit, but it is worthy, because God says, “godliness with contentment is great gain.”

I don’t have everything I want, but I have everything I need, and that’s enough.

Immigration and Racism

I was having a discussion online (I know, always a bad idea).  The discussion centered on this article. One person made the comment, “ignorant people. They’re hard workers and u all have no idea how tough it is in other counties educate yourself before making racist comments. Trust me if they could become legal that easily they would.”

I immediately had two thoughts about this comment.  The first thought is this: What is it that makes people think that if there’s something good out there, and you can’t get it legally, it’s acceptable to simply take it?   Because that’s what illegal immigrants are doing. Is it wrong to want to be a citizen of the United States?  No.  Is it wrong to STEAL citizenship?  Absolutely.

The second thought is this:  If you accuse someone of racism, and they aren’t being racist, what does that make you?  Seriously, though.  If you are Hispanic, and you look at a white guy and assume that his reaction to something is based on racism BECAUSE HE’S WHITE, that makes you a racist.  Plain and simple.
