Hi Guys I just registered and paid for the information literacy course today. Can I start it now or do I have to Wait till NOv. 5th for the semester to start. Can I download the material now and get it organized then take the test or have to wait to do that too. Thank you! Cindy

Ok, first things first. Be sure to write down on your scrap paper the information given to you at the beginning of the exam. You are given various significance levels and the appropriate Z score. They write it in an unusual way. It is written as follows:

Z. 0.0050 1.96
Z 0.010 1.645

You need this data to answer four or five questions in which you are asked about significance levels but not given the critical z-score. That’s why you need this information.

There were no questions, on my exam, that required you to calculate the correlation coefficient ( r ). There were two questions of this type: What can you say about the relationship of x and y if r = -0.80. Answer: strong and negative, although the answer on the exam used the word inverse, not negative. There was also a question that asked for the formula of the correlation coefficient of non-determination. I believe that was 1-r^2. There was also a question that asked what the correlation coefficient of determination tells you?

There were a few questions on the regression line. Again, no questions asked me to calculate the slope or y-intercept. I had questions that asked about the line. Given y = a + bx. What is b? Answer: the slope. What is a? Answer: the y-intercept. Then there were two questions, I believe, in which they gave you a value for x and asked you to solve for y. Very simple stuff there.

There were a few questions on hypothesis testing. I believe there were two questions that laid out a scenario then asked you to select the appropriate null and alternative hypothesis. There were one or two questions on p-values. Specifically, given the p-value of 0.034 and a significance level of 0.05, what would you say about the hypothesis. Your answers were to reject, do not reject and two off the wall answers. The answer is reject since the p-value is less than the significance level.

There were a few probability questions. One question was the following: You have 3 red balls, 2 yellow balls and 5 green balls. You select one ball, write down the color, and then place the ball back in the group. If you repeat this procedure 1000 times, how many red balls would you expect to draw? Answer: 300. Since there are 10 balls in total and 3 are red, you would have 3 in 10 chance of drawing the red ball. So, if the experiment is repeated 1000 times you would expect 300 red balls to be drawn. Another probability question was: Maria goes to Café A 60 percent of the time and Café B 40 percent of the time. Regardless of which Café she goes to, she orders the café moca 50 percent of the time. What is the probability that Maria will go to Café A and order the café moca? Answer: Since this an intersection of events and they are independent of one another, we use the multiplication rule. So we multiply Café A probability, 0.6, by the probability of ordering the café moca, which is 0.5. Answer is 30 percent or 0.3. The next probability problem was: Voter A votes 45 percent of the time, Voter B votes 30 percent of the time and Voter A and Voter B vote together 20 percent of the time. What is the probability that Voter A or Voter B will vote? Answer: You use the addition rule for non-mutually exclusive events. So, 45 percent + 30 percent – 20 percent = 55 percent.

The final part of the exam was easy. There were questions that related to the normal distribution so you need to know that 1 standard deviation = 68%, 2 standard deviations = 95% and 3 standard deviations = 99.7%. There was a question that said: the population mean for the height of women is 60 inches with a standard deviation of 2.5 inches. What percentage of women will be between 57.5 and 62.5 inches? Since this is 1 standard deviation below and above the mean, the answer is 68%. Then they ask the same question but ask, what is the percentage of women between 57.5 and 60 inches? Since this is one standard deviation below the mean, but not above the mean you would take half of the 1 standard deviation amount. Thus, the answer is 34%. Another question gives you a mean of 100, standard deviation of 0.5. What is the range of values when looking to contain 95% of the population? Remember, 95% is 2 standard deviations so the answer is 99-101.

Just buy Idiot’s Guide to Statistics and study it thoroughly and you will do fine on this exam. Take the time you need to study, and you will be just fine.

I have taken both the DSST practice tests for this exam. I am wondering since neither practice test showed actual memos, reports, etc... does the real test or does it just ask you about them like the practice ones did? I am going to try and take this Saturday.

Hello, I took English comp w/essay about a month ago and did really bad. (Not posting score) My next thought was to take a course. I'm going to have my credits transferred to TESC. I'm required to take English comp w/essay. I'm really open to any ideas. I would like to stay with something online. Thank you for your ideas!

I'm close to completing my undergrad and I've started looking for a graduate school. My goal is to earn an MBA with a focus in Human Resource Management, to complete it in 2 years or less, all online. I'm considering Aspen, St. Leo, California Coast, and Western Governors, to name a few. So many good ones out there, what's a girl to do?!?

I know it won't be a breeze but I was wondering, are the courses difficult to complete on your own (I'm nervous)? Does the school offer enough support if you get stuck? How long are the courses, are they self-paced? Please share your experiences with graduate school.

First off i would like to say hello to everyone on this form and thank you for taking the time to look over my post and hopefully give me some advice.

Ok, I'm a 24 year old Border Patrol Agent with obviously no college degree, that would really like to get one as fast and as cheaply as i can (who doesn't). I have about 50 community college credits strewn out over 3 colleges . I also graduated from a 17 week academy at FLETC (Federal Law Enforcement Training Center) that hopefully I can get some college credits for. Other than that, that's it.

My question is, from where I'm at what am I looking at timeline wise and cost wise to get my BA and what colleges would be the best. Can some explain to me what a portfolio assessment is and if its something that someone with LE experience or military experience has used and was able to get college credits for?

I don't have a lot of time to take online classes and would like to "test out" on as many classes as I can, I'm usually a very good test taker. What is the best rout for doing this?

Thanks alot guys.

Passed with a 74! I wrote an entire page on what I found on this exam, but it did not upload to this forum. Oh, well..LOL.

Advice, buy Idiots Guide to Statistics. Study that book for a few weeks then use the instacert flashcards to test how much you learned. This test is more than doable. So good luck to all that attempt this exam.

On the first attempt, I missed it by three points...(painful). I still need 6 UL credits and decided to take this exam again...:eek:! I plan to take it next week on Friday...double-eeK :eek:!!

I'm studying IC + the tips on the exam specific page. Does anyone have any additional study notes for this one? Anything will be greatly appreciated!

Does anyone know if there are any Spanish literature and history/civilization courses that can be done online or via independent studies [examinations]?
I only need 6 credits in Spa lit. and 3 in Spa history/civil. for my B.A in Spanish, but I am not able to find these courses online or by examination etc.
If anybody has a clue, I would appreciate it.
By the way, the Ohio University examinations wouldn't work because they are based on translations as opposed to originals in Spanish.
Thanks in advance.

I just wanted to give some input for those going this route in order to get College Algebra credit for the Excelsior Business Degree. The Technical Math I course is broken down into 6 sections. You get a booklet for each section, which contains study and review material and a 20-25 question multiple choice test at the end. When you have completed the test, you go online, fill in the test answers and voila you get your score.

Now the way your grade breaks down is important. Your final grade is 2/3 based on the average of your 6 section tests, and 1/3 based on your final exam. As I sit waiting for my final exam to arrive, I've managed an 85 average on the 6 sections. So 2/3's of my grade is already set at an average of 85. A passing grade of a C = 75 points. So using my new found Math skills, since the final grade is 2/3 sections and 1/3 final, and a passing grade is 75 out of 100. Then I will need a combined score of at least 225 for the three parts that make up the final grade. Since I already have an 85 average for each of the first 2/3's of the grade or 170, then all I need to pass the class is to score 225-170= 55 on the final. Now if I score less than a 55 on the final, I am still able to retake it, with a maximum top score of given of 70.

Here are the sections:

Formulas
Algebra Pt 1
Algebra Pt 2
Algebra Pt 3
Logarithms
Metric System

Here is the good news: The tests are OPEN BOOK. The final is OPEN BOOK, but timed. On all tests including the final, you can retake and get a maximum of 70.


Here is my advice:
You can do them in any order. If you are as rusty at Algebra as I am, you'll need to take advantage of every angle, and maximize your scoring ability.
There are three sections that with preperation you should nail and score close to 100. The Formulas section is basic. The Logarithm section takes a while to figure out, however you do have a calculator as backup to help you out. I repeat you have a calculator to help you out. The Metric System is the third very doable section.

So if you do well on those three sections, then you have some margin of error on the 3 Algebra sections.

Now the final is only 25-30 questions.... and since the final reflects the 6 sections, then if you know the Formulas, Logarithms and Metric System, then it is quite possible to pass with less than stellar Algebra skills.

I'll let you know about the final when it comes.
