1) Initially I was apprehensive about doing this course. I was apprehensive because I’m currently deployed, but moreover because it’s a math course. I’ve stated before math is a finite skill, though it’s something that can be learned in with consistent practice I wasn’t sure my schedule would allow for me to dedicate enough time towards my success. However, the ALEKS program made it easy for me to learn at my own pace, and provide the guidance to set me on the right path for success. Overall I expected to remaster skill that had faded from taking years off of doing math on a regular basis, and that’s exactly what happened. I think reading the explanations and doing as many practice questions as possible ultimately contributed to that success, and I commend the professor for being so engaged with her students. I know on a few occasions I emailed her about the problem sets that may have been confusing at the time or had to ask for assistance in other areas, and she was always very prompt in responded back to me, and always very encouraging. I’ve had online professors in the past that you could just tell didn’t put their full effort in to the students success, so it makes it a lot easier when you have someone like Dr. Grubert on your sideline cheering you on. There’s nothing I would have done differently in the class, I think it was all set up to be very” user friendly” if you will.

2) So initially I felt really nervous about this course and a little intimated about MATH in general. I really didn’t know what to expect but I knew that it was going to be unconformable and that’s exactly what I was expecting. This course has really matched what I wanted to experience in this class. It has really allowed me to move at my pace and this has been good for my my work schedule. What has worked the best for me to learn has been the ALEKS program itself, the way it’s setup with videos and features, etext book really gives you many options to assist. The process of the course coupled with the quick communication really made me feel that the professor is truly there for us and will work with you no matter what you have going on. So I would have brushed up on my math since it has been so long since I touched any Math. There was nothing anyone could have told me other than having some experience with an online course.

Yes and no. All continuous information has the median, status and mean. Yet, strictly speaking, ordinal information has the median and status But, and nominal information has just one status. This manner is the least used of these methods of central tendency and can only be applied when dealing with specified information. For this reason, that status can take the greatest method of central tendency (as it is the only one appropriate to take) when dealing with specified information. These mean and/or average are normally chosen when dealing with all different types of information, but that does not mean it is never used with these information types (Woods, D., Jan. 2018).

Are the standard deviation or the interquartile range factors? The standard deviation is a measure of the degree to which an individual’s knowledge or understanding about a topic is related to its level of relevance. In other words, if you know something about a topic but don’t know much about it, then you probably have no idea what to expect from your research on that topic. This means you can always find out more about the subject by reading books, articles.

Hello classmates and professor,

The question I decided to answer for this discussion is I read in the newspaper that a study of a new drug for cancer “increased survival by an average of eight weeks.” It turns out that this is a median, and it is used for complicated statistical reasons. But in a perfect world, would you prefer to know the increase in mean or median survival? In the perfect world I would prefer to know the mean vs median. Like Andrew Vickers mentions at the end of the video, “means are good for decision making, medians are good for describing data”. When it comes down to something that a dangerous and life threatening condition it’s probably best and most comforting to know the average survival versus a number that’s calculated by the “middle”. Median is something that results in a number/value and cannot appropriately calculate the survival rate for someone with cancer.

1. “Conceptual Error: For Me the Conceptual Error is the one that I most relate too. I believe going back to when i learned Math in high school, and not fully being able to understand the problem on its entirely. having the one on one communication with the teacher. a successful student understands mathematical ideas, and had the ability to transfer its knowledge into new situations and apply them. Now, using the Aleks Program I try to understand the program but, when is time to solve it i end up with the wrong answer. For me it is very difficult to understand it just by reading, even though, a video helps I am more of a people’s person (interaction), therefore It takes me as twice as long to solve the problem and if I do find the solution usually its the wrong answer. Practicing Consumer Math 1 for me was kind of easy, however graphs, function and system is giving me a headache and Its making fall behind the course. I think that if I want to prevent conceptual errors its not going to be easy, I will need to more time to explore and discover a new math concept in a way that will help me see and understand the why.”

2. “The error that I make most often is conceptual. I have difficulty comprehending the question especially word problems. I HATE! them. Because of this, I spend a lot of time getting problems wrong and repeating them. As a result it takes longer to complete an assignment. Perhaps this is why I do not enjoy math. This was the case last week. It took a long time to reach the minimum goal because of it. When a problem has numbers and symbols I can figure out the concept. The only way that I can figure out how to conquer this is by reading out loud and trying to understand the vocabulary words. I do not have this problem in other courses“
