Today’s a bad day.

I failed my Statistics 101 midterm with a score of 44%.

2/4th of the material covered in the midterm, I understood well. 1/4th of the material was completely unknown to me (because I couldn’t stay on-track with the readings). 1/4th of the material was hard because there was math involved and when it comes to the math they cover in class... I don’t get it. I don’t understand it (not because I'm stupid, but because the literal WALLS OF TEXT/MATH they present to me and expect me to understand basically grind my mind to an absolute snails pace... hence me not even being able to keep up on reading. Today, I ran out of time and was forced to take the midterm (or risk getting a 0% score for not even attempting it before time ran out).

Am I sad? Yes.

It’s one midterm. I failed. It was 25% of my overall grade.

I’ll try harder next time... but not without help. I’m going to seek out tutoring, someone who’s willing to work with someone with ADHD. I’ll get through this, might even pass the class with good marks. 

Statistics is NOT OPTIONAL for me, not if I want to go and get a Ph.D. So, learning it now will help me during my Ph.D/Psy.D, therefore, the expense of tutoring is justified and not impulsive. In fact, It would be impulsive to simply brush off the low score, I think.

The other issue that I've identified is that the medication I've been on isn’t working as well... at first, I thought it was just me, that I could simply PUSH THROUGH even without the medication (yes, I know, it was stupid of me to think this way). Good news is: I talked to my doctor today. She’s going to change my meds and I’ll see how they work out.

The one thing I know is that I'm not going to give up, be sad, get drunk, and cry the night away. Nah. I got important things to do. Can’t be a Psychologist if I put myself down like that.

3. Probability

Gain an understanding of probability theory and its application in statistics. Learn about probability distributions, including the normal distribution, and how to calculate probabilities.

4. Sampling and Sampling Distributions

Explore the concepts of sampling and sampling distributions. Understand the importance of random sampling and the central limit theorem in making inferences about populations.

5. Hypothesis Testing

Learn about hypothesis testing and its role in statistical inference. Understand the steps involved in hypothesis testing, including formulating hypotheses, choosing a significance level, conducting tests, and interpreting results.

6. Confidence Intervals

Discover how to construct confidence intervals to estimate population parameters. Learn to interpret confidence intervals and make inferences about the population based on sample data.

7. Correlation and Regression

Understand the concepts of correlation and regression analysis. Learn how to measure the strength and direction of relationships between variables and how to build regression models for prediction and inference.

Too lazy to read the textbook, so reviewing standard error via. youtube and the guy keeps giving "pep-talks" that are making me want to stab myself in the eye.
