Today’s word for Just Jot It January is "possibility," brought to us by the lovely and talented Jill at J-Dub’s Grin And Bear It. Thank you, Jilly-Willy!

I took the plunge recently and decided to take a course in Data Science from Udemy. Data Science encompasses many different skills, including (according to Udemy) "Statistical analysis, Python programming with NumPy, pandas, matplotlib, and Seaborn, Advanced statistical analysis, Tableau, Machine Learning with stats models and scikit-learn, Deep learning with TensorFlow."

I’m roughly 18% of the way through the class, which up to now has dealt with statistics and probability, a subject I excelled at in college and, amazingly, I still know a lot about. Meaning, of course, this part of the class is very dull. Painfully so…

Whenever you talk about elementary probability, the easiest example is a coin toss. When you flip a (fair) coin, there are two possible outcomes, heads or tails, both of which are just as likely to occur, thus giving the probability of either as .5. Over an infinite number of tosses of a coin, heads will come up half the time, and tails will come up the rest of the time.

Now, heads or tails are not the only two possibilities for an outcome. The coin might land on its edge, or it could fall on the floor and roll under the couch or onto and off of a porch, or the cat might decide, as is often the case with a small, moving object, that it’s a toy and chase after it. The probabilities don’t consider those possibilities, because we aren’t interested in whether those things happen. If one of them occurs, we retrieve the coin or get another one, and continue as if nothing happened…

Now a word about Light Powder Arrid spray deodorant. Do something really dry for your underarms!

I’d put my bet on the cat 😊

Stats are a hard concept. I got lost during the lesson about permutations and never recovered. Out of your course outline beside stats, I’ve only heard of Tableau. Now Tableau … that I’d like to learn. The rest is all huh?

I have heard of Udemy but haven’t looked at any of the classes yet. The one you are taking is not something I’d look for. Hope it gets more interesting for you soon!

Stats was my worst course in University and everything you wrote made me feel like I am standing in the corner with. Dunce cap on. Lol. I am certain your course will get more interesting for you as you progress. Good for you to try something new.

I sincerely hope so. I think I’m pretty near the end of the statistics portion of the class, so I should be getting into some of the good stuff soon.
