This class is not as easy as the review before me may suggest. The class is based on a curve and if you perform at the class average on the mid-term or final, you get a C on the exam. I was able to perform above average the first time by 0.54 on the mid-term and then by 1.20 on the final so I got a B on the mid-term and a borderline A on the final. I did the SONA extra credit which is 3 points added on the final. For the mid-term he asked one extra credit question which was worth 5 points max; it asked for the probability of getting a “Royal Flush” in a deck of cards. I didn’t get the right answer on this extra credit question but I worked out the question and explained my reasoning. However, the TA gave me a 0/5 on the extra credit which I found a bit harsh, as the professor was lenient on the extra credit on the final. It is not an all or nothing problem, but the TA graded it that way. On the Final I got 7/10 on the extra credit, which was 2 5-point questions. Looking back, the final was way easier than the mid-term so focus on the mid-term. The professor is generally alright though his lectures can be a drag. Good luck guys and I hope this review helps you all planning to take this class with this professor in the future.

He’s a little boring, but if you’ve taken AP stats you will be fine. Even if you haven’t, all the concepts are simple enough that you can khan academy it. He’s very chill and he says his exams are hard, but I didn’t think so? It’s like 10 true/false, 30 or so MCQ and a handful of short answer, with sizeable EC. He has an online study guide (or at least my TA did) and it just had run of the mill practice problems you could find online. Also

TLDR it wasn’t awful I wouldn’t worry about it if you know even a little bit of stats

This class was a drag and bore. I hated every minute of it. Most summer classes are easy, but this one just was not. The professor spends more time telling you about his time at CSUN and gets off topic real easily. There is no homework or assignments. just graded on tests and attendance.
The tests are extremely and I mean extremely hard even though there is a curve, it's bull. His grading scale is also pretty wack.
Midterm and final weigh the same. The pop quizzes are not easy cause if you dosed off in class you're screwed. Never had enough time to actually complete the quizzes either.

While there may have been easier stats classes (especially during the regular quarter), I left this class knowing a good foundation of stats and a better understanding of research methods tbh. I regret not studying more, so make sure you start on the study guide like a week in advance. The stats book he uses is online and isn't particularly helpful because he goes over most things in his slides (and it's a bit easier to understand). The tests are 10 t/f, 15 mc, and 5 "written" (i.e. problems with multiple steps). Do ALL the extra credit (studies and problems on test). There's pop quizzes but I'm not sure how they are graded.

Dr. Ainsworth will tell you that his exams are VERY difficult, but that's the furthest thing from the truth. The majority of the multiple choice and true/false questions on the exams require you to understand the concepts presented in the slides at surface level, while only a few questions test your deeper understanding of the material. The practice problems he gives you on the practice midterm/final resemble the difficulty of the exam. I would strongly suggest memorizing how to do those problems, as a few of them will show up on the midterm. In terms of the midterm, he doesn't lecture much about probability, but a lot of questions are based on basic probability concepts. The math in this class does not go beyond addition/subtraction/multiplication/division/square roots/squaring, so you should be more than fine with little to no math background. The equations for ANOVA and the sample testing can be a lot, but he gives you all the tables and equations you need on the exam.

If you are OKAY with math, I think getting an A is a reasonable task in this stats class. The examples might look overwhelming at first, but if you review them again and again till you remember each step, the exams aren't that tough. The professor doesn't play any unexpected tricks in midterms and finals. In fact, the questions are very straightforward. But you really have to get a hold on every word in the slides, since there are truth or false questions regarding abstract definitions. In addition, I believe the extra credits helped boost the grade a bit, since it's 3 points directly added to the curved grade. The professors is a good lecturer. And he handed out equation sheets in exams, which are the most important things we needed. Also, no homework, so light workload for someone who really understands the material. By that I don't mean being a math genius but more importantly, master the lecture slides!

The last review seems to be a bit salty about their grade this Summer. I understand that there are some people who simply aren't good with a little bit of math. However, please do not use "international students" as an excuse for your inability to use the equations sheet that Ainsworth PROVIDES for each test. I don't often write reviews for classes, but after reading the last comment how could I not.

Pros: Equations sheet provided in class, Book is provided online and FREE, no homework, tests are non-cumulative.
"Pop quizzes" this summer were merely to get you attendance points for lecture. I literally had 1/5 on the 2nd pop quiz (out of 2 quizzes we had) and still received full points for the quiz portion of the grade.
Cons: Email responses weren't very timely nor helpful.

Overall, reading the book will help you on some multiple choice questions, but as long as you master the equations then you will be fine. For the midterm, read the probability section of the book which will get you a few points on MC. The midterm covered the basics of math in general (SD, mean, median, mode, etc. some probability, and t-tests and z-scores) The final was pretty much only about ANOVA's with some correlation/regression. This is a reasonable amount of subjects for a class with only a midterm and a final. Just know what information is being provided and which equation is appropriate for the Short Answer portions of the tests.

tldr: Easy if you are relatively good at math. "Hard" if you don't know how to use equations and don't pay attention to what symbols mean.

This class was exceptionally hard. I hated every minute of it. Summer classes are always easier so im glad i just passed the class. The professor is cool he kind of moves through things pretty quickly. There is no homework or assignments. just graded on tests and attendance.
he has 5 pop quizzes (only did 2)
uses Socratic (a polling website) for attendance, meaning you can literally answer the questions from anywhere and get attendance credit.
The tests are extremely and I mean extremely hard even tho there is a curve all the international students set the average. tests are 25 MC and like 5 free response questions. And 1 or 2 extra credit problems at the end.
Midterm and final weigh the same.
pop quizzes are not easy cause if you dosed off in class you're screwed. Never had enough time to actually complete the quizzes either.
I would never be taking this class again so thats what I am happy about.
Also the professor did not drop the grades until after the first week of session C classes. SUPER ANNOYING. I was enrolled in psych 100B for the whole week wondering if I even passed 100A.

Professor Ainsworth is one of the realest professors out there. Every word that comes out of his mouth is genuine. He talks to us as if we are normal people, not just students. He makes his lectures very interactive; it's like he is having a conversation with us. Although some are annoyed by his personal anecdotes, I actually appreciate them.

Your grade will consist of Participation, Quizzes, Midterm, Final.
Participation + Quizzes are practically free points if you attend all lectures. He will drop 1 Participation grade if you miss a day, as well as one quiz if you miss one. He says he stresses attending lecture and actually doing the quiz more than getting a good score on the quiz; and he means it. It doesn't matter if you do bad on the quizzes because he has a formula where what mostly all that matters is being present and completing the quiz (confusing I know, but it will make sense towards the end of the class).
The midterm and final consist of True/False, Multiple Choice, and Free Response questions. He says the Midterm and Final are difficult exams. I agree, but what will save you is the EXTRA CREDIT. On each exam, he has extra credit questions at the end. Do them ALL. The reason they're so valuable is because he adds on the extra credit AFTER he curves the class. For the exams, make sure you know the 7 hypothesis testing steps. Study and know the lecture slides in and out, because there are conceptual true/false and multiple choice questions that can be difficult if you don't know the concepts well. That being said, for our class, he actually doubled the amount of points the multiple choice was worth, so doing well on the multiple choice was more important than the free response (Multiple Choice: 25 questions, 50 points... while Free Response was 25 points).
Aside from extra credit on exams, he has two more extra credit opportunities. One being participating in SONA, and another being completing his survey towards the end of the class. Do both. They're worth about ~3% of your grade, and they are easy points.
Overall, I really liked Dr. Ainsworth. He is a funny person and will take time to answer students' questions thoroughly.

I thought that because I have taken previous statistics classes, this class would be a breeze. I was wrong. The professor is a really nice guy, who usually teaches at CSUN, but the exams were very difficult. Both lecture and discussion participation counted (sign-in sheet), there were also pop-quizzes in class, one midterm, and one final. He did allow for some extra credit from SONA participation, but it is only a few points. Do not underestimate this class
