TAKE THIS CLASS.

For whatever reason you have to take 100A for. This is the professor tot take it with. Dr.Ainsworth is concerned and wants everyone to get good grades. He is straightforward and his tests reflect that.
Make sure your TA is Anthony. He is amazing and is vert good at breaking down the difficult concepts. Best TA I have ever had at UCLA.

Tests:
A midterm and final.
Non-cummulative and he gives you a cheat sheet for the final. Know how to apply the equations and know the conceptual facts on the slides.
Slides are the most important thing. If it isn't on the slides, it won't be on the test.
If you know how to do all the practice problems then you will be fine.

Book:
Unnecessary unless you are really confused. I never read, didn't even buy the book.

Extra Credit:
DO IT! it boosts your grade up A LOT.
Sign up for SONA tests as early as possible and get those 3 extra credit points that are added at the end when your grades are added together and can boost your grade up a whole letter grade.
You also get a point for doing the class eval.

This class is a win-win.
Also, taking stats 10 before taking this class can be very helpful but not necessary. I know people that got As without ever taking stats.

Ainsworth is a pretty cool guy. He comes in the summer to teach 100A (he teaches at CSUN normally). He makes jokes and his slides aren't too hard to follow. The TA also helps debunk some of the material. I think this shortened summer version of 100A is a win win. To me, it seemed not too hard and very doable. Just do all the practice problems they give you and if you know how to do all of those, you are doing just fine. He does offer extra credit.

Ainsworth is the only professor that teaches 100A during the summer. Honestly, I came into the class scared out of my pants because I have NEVER taken a statistics class ever! However, it was actually more doable than I thought it would be. He talks about concepts a lot in lecture, but omg, only remember those that are important because the rest are pointless. .. The only important thing you really need to know are the equations and finding F, t values. Know how to conduct all the analysis tests like ANOVA, factorial, regression, etc. THOSE ARE THE THINGS THAT MATTER MOST! If you understand how to apply the equations, then you will understand the class.
So like the person below mentioned, grade depends on the midterm, final, quizzes, and participation. DO THE EXTRA CREDIT!!!! DO ALL EXTRA CREDIT! I honestly would not have gotten a B in this class if there was NO extra credit !! I failed the midterm and was sh**ting in my pants because I thought I was going to fail the class, but thank god I did well on the final and did all the extra credit on the tests as well as the psych study extra credit. But yes, so its a DOABLE Class! do all extra credit and know how to apply all the equations and you should be fine (:

I have mixed feelings about his class. He teaches 100A in the summer. I've taken a statistics class before, which definitely helps.

Your grade consists of:

Participation: This is very liberally graded, basically go to lecture and use the clicker for attendance and occasionally go on the online book and you'll get full points.

Clicker quizzes: They're 5 question clicker quizzes that are pretty easy if you pay attention.

Midterm/Final: They're not easy, not going to lie. It's True/False, multiple choice, and free response. Understand the concepts well and know how to do calculations. Memorize them and they eventually become engrained in your head. Work quickly and accurately. Know how to do his 7-steps of hypothesis testing.

Midterm/Final EXTRA CREDIT: These will help you so much. You basically add on any EC points onto your grade AFTER he curves it. So they're very beneficial. Do them if you can.

Extra credit: He offers extra credit in weird things. Like for participating as a subject in Psychology research projects and answering a course evaluation at the end of the quarter. Easy points if you ask me.

If it weren't for the extra credit I wouldn't have done so well. I've taken stats before, but I didn't take this class seriously so my performance did not reflect my knowledge of statistics. The extra credit saved me; I got back 20+ points that do not affect the curve.

His grading is weird. He uses z-scores. Basically using the mean and standard deviation, you get a z-score based on your raw score. anything above 1.04+ is an A-, anything above 1.25 is an A. This is where extra credit helps because you tack it onto your raw score and you can go up 2 or 3 grades. On a midterm I had a z-score that equates to a B+, but I got a shitton of extra credit and it boosted me to an A+.

Take this class seriously if you don't want to stress out about it at the end like I did, but know that you have some slack in terms of extra credit. He's a really nice guy and he cares.

Ainsworth is not that bad. He graduated from UCLA but teaches at CSU Northridge during the regular school year, so he only teaches 100A during the summer at UCLA. He says that he tests on lecture material and material from the book, but all you really need to do is study the lectures slides really well. There is only 1 midterm and 1 final that are worth 50% each, so make sure that do decent on the midterm so you can at least pass the class if you do well on the final. The tests consist of true/ false, multiple choice, and short answer questions, which are pretty easy if you study the lectures really well and thoroughly understand the material. The class is also curved, but since the tests are not that hard and people do well, then basically your grade is your grade.

Just study the lectures slides, do a lot of examples from the book and you'll be fine!

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

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.

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!

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.
