Calculator Question

If buying a calculator for statistical analysis, would you buy a Casio or Texas Instruments? And which one performs linear progression and standard deviation calculations?

 

Nonsensical

 

Linear progression? Not regression?

 

Maybe check the Scientific Calculator Forum ? Sorry, couldn’t help myself!

 

What's wrong with using your phone?

 

That’s a great idea! Seriously.

 

TI or HP
I was an engineer major long....long time ago. I used Probably an abacus back then compared to what the technology offers today. Go with TI.

 

Are you planning to analyze the people's preference on roast vs. mashed potatoes?

Joke post aside, above poster is right: TI is the standard for a reason. I still use one in my day to day job (scientific one, but I think you need the graphing model for what you described above).

Also, I'm not sure if these posts are proving or disproving your claim that forum threads should be on topic. What does RockLobster say? He's the resident expert on topic derailment.

 

Back in my day, everyone who was anyone used an HP 12c

 

HP-15C... Showing my age.
I know the point of this but dang if it didn't bring back some ancient engineering info..

 

Had HPs but have also been a TI fan.

 

The cool kids all use the HP-15 with the magnetic strip reader. Only nerds use TIs...

 

Don't answer him. He's throwing a hissy fit because he got called out!!

 

alight had to dig out the archives being that I was so mobile back in the day before gtfo....ing

 

wtf!

 

Just about any modern calculator will work. I have both TI and HP...both are good and work well. Never worked with the Casios.
HP15C (1985) is on my work desk....my HP48GX (1996) is at home and rarely used. Best is the "DROID48" app (today!) on my android phone...really handy and the one I've used the most.
And when the youngsters start acting up, I'll hand them a LED TI30 (1977)....and to really blow their mind, I'll pull out the mechanical handheld calculator CURTA (1963) or the typewrite sized mechanical Walther WSR 160 (1965) calculator (which has a mechanical memory register!).
****If you are taking a class, get the same calculator your instructor has, or one model newer/higher. Just make sure it's allowed on the exams you'll take. **** (My advice as a former mathematics/calculus instructor).
I'm a recovering engineer with toys...and a very understanding bride...and one day, I'll post what I've done to my 4Runner (just starting to build after spending 3 years reading about everyone's builds for ideas and lessons learned).
I'm partial to HPs...or at least the ones that were built like tanks way back in the 1980s era...but getting whatever your teacher has means they can show you the keystrokes when you get confused

PS/Edit TI publishes a lot of instructional material with examples and answers for High School classes ( and then later for college level courses) ...it's how TI made huge gains into the college engineering community which were virtually all HP from the 1970s until the 1990s. So there is a lot of info and example problems for TI out there. Now, calculators can switch between the AOS and RPN methodologies of using the calculator. Once you learn RPN, you won't want to use AOS calculators...but there is a bit of a learning curve.

 

Reverse Polish Notation...

 

I have the same TI 84 Plus & still use it.

 

Buy an RPN and be done with it.

 

What's an RPN?? I have an iphone that calculator is fine for me.

 

Reverse Polish Notation, its easier once you get the hang of it. Calculations take seconds with less inputs.

 

Yeah I just watched a video on it.

 

I always found TI easier to use. Probably because it was hay my instructors used along with finding tip sheets was easier for the TI at that time. Looking back at it I think it’s like a Ford vs Chevy thing and becomes personal preference.

 

Back in the 80's (yeah I know - I'm old), our mission was to track submarines. We had to check out/sign for the HP calculators we would use to crunch the
numbers while tracking. The program strips were classified "Secret" - they held all the data on the subs and allowed us to enter measurements and get
their speed/depth/course, etc..... Pretty cool (back then).

 

Dam what is this calculator thing you folks talking bout? We use fingers and toes, well cousin jimmy he can't count beyond 15 as he lost his foot (don't worry we still looking for it), so we don't ask him to figure our wages.

Seriously, I have bought TI, but with apps for the phone, I would only buy a calculator if I was not allowed to use my phone in a class.

 

TI89 at least.. got my Mech E degree with it. Thermodynamics, fluid dynamics, linear algebra, prob & statistics, all of the calculuses, you name it

 

I remember in highschool i was required for a Math class to buy a TI-86. My parents were pissed because that was like an $80 calculator back in the late 90's. Still have it in a box somewhere.

 

They still require it. My daughter had to get one. I asked why they couldn’t just use their smart phone which is much more capable.

 

Required. That’s funny. In my day pocket calculators were new, expensive and controversial. At first their use was forbidden outright. Calculations were to be done by hand, showing work (or with a slide rule, go figure,) The next year, as prices came down and more people could afford them, calculators were approved for homework, but forbidden on quizzes and tests. By the time I was in college they were required. Pretty amazing. Forbidden to required in 4 years.

 

I remember back when I was in engineering school (mid - late 1980's) what calculator you had was kind of a status symbol. Plenty of people had the top of the line HP and TI graphing models. They were cool, but not necessary - at least back then. I had a TI-35 - and then later a TI-55 - neither of which was a graphing model. Got through a mechanical engineering degree and never really needed anything better than a TI-35. I'm still an engineering manager at a fairly large engineering/manufacturing company. I've had a cheap TI-36X Solar on my desk for the past 20+ years (same one) and I've never had a situation where I couldn't calculate something because I didn't have a good enough calculator. Pretty sure I wouldn't have gotten better grades with a more expensive calculator
