Types of Questions There are 6 types of questions that you will need to know about when using WebAssign in this course. They are: multiple choice, numerical, fillintheblank, pulldown menus, multiple select, and symbolic. (a) Multiple Choice Multiple choice questions are like most of the ones above. There is always one correct answer. How many correct answers are there for a multiple choice question? (_) (_) 0 (o) (o) 1 (_) (_) 2 (_) (_) 3 (_) (_) it depends on the question Viewing: Last Response View: All Responses Notes (b) Numerical Numerical questions have "short boxes" which require you to enter a number as the answer. To be safe you should never enter letters or symbols in a numerical answer. If you get a warning that WebAssign "could not understand" your answer check and make sure that you did not enter letters or symbols. Instead, you should use your calculator to get a decimal approximation. WebAssign will accept answers within 1% of the correct answer. (See part (a) of #3 What is 1/4 times 5? 5/4 [1.25] (c) Fillintheblank Fillintheblank questions look below for more details.) identical to numerical questions. The only difference is that you will be entering a word or words as your answer. Your answer must be spelled correctly to be graded as correct. What is the capital of North Carolina? raleigh [Raleigh] (d) Pulldown Menus Pulldown Menus are a special kind of multiple choice. Like multiple choice there is only one correct answer. To select your answer click on the pulldown menu and pick the correct response. Complete the statement below. 100 = [ = ] 102 (e) Multiple Select Multiple Select questions are always "tagged" with the statement "(Select all that apply.)". There could be multiple correct answers, but there might be only one correct answer. To select your answer click next to all of the correct responses. Which number(s) are less than 1000? (Select all that apply.) [x] [x] 10 [_] [_] 3000 [x] [x] 500 [_] [_] 6000 [_] [_] 1000 [_] [_] none of these [x] [x] 3 (f) Symbolic Symbolic questions require you to enter your answers using symbolic notation (like you would use in your calculator or Maple for example). These are answers that contain variables or special symbols. You can recognize when a symbolic answer is desired because you will be given a "long blank" with an "eye" symbol at the end. Symbolic questions are so special that there are multiple assignments througout the semester that will teach you how to enter your answers, etc. You have determined that the answer to a problem is y = 3x. Note that the "y =" is already given. Enter 3x or 3*x as your answer. (Note that symbolic answers are case sensitive so you must enter 3x or 3*x and NOT 3X to be graded correctly.) y = 3*x [3x] pts 1 1/1 2 1/1 3 1/1 4 1/1 4/4 subs 1/20 1/20 1/20 1/20 3. Notes on Entering Answers (a) 1% Tolerance with Numerical Answers For questions with numerical answers, WebAssign is pretty generous about accuracy. While some questions will specify that a certain degree of accuracy is required, most questions for which a degree of accuracy is not specified will be graded as "correct" if the answer you give is within 1% of the correct answer. Some examples Viewing: Last Response View: All Responses Notes are shown below. ** Below you are asked to give a decimal approximation for 2/7. If you answer .28 your answer may be graded as "wrong". The reason is that the "error" here is 2/7  .28 which is about .00571, and this error is 2% of the actual answer which is 2/7. (The percentage error is .00571 divided by 2/7 which is .02.) Your answer will be graded as "correct", however, if you type . 285 or .286. Try it. 2/7 = .285 [0.285714285714286] ** You can't think of the level of accuracy in terms of "number of decimal places". With big numbers, you can get by with what appears to be pretty crude approximations. For example, you will be graded as "right" if you answer 10000 to the following question. Try it. [Note: In numerical questions you should never include commas in your answer, i.e. type 10000 and not 10,000.] 5000 + 4950 = 10000 [9950] The reason you can get by with an answer that is off by 50 is that 50/9950 = .005025, so the error is only about 0.5% of the correct answer, and that is within the range of the 1% accuracy requirement. (b) NONE Sometimes you will see a question that has a note similar to the following. Find the intercept. (If there is no intercept, enter NONE.) So if there is a numerical response to the question you should enter the decimal approximation, otherwise you should enter NONE as your answer. You must spell NONE correctly. Try entering NONE below. NONE [NONE] (c) INFINITY Sometimes your answer (or part of your answer) will be or . This is obviously not something that you will find on your keyboard. Instead you will need to type the word INFINITY or INFINITY. Anytime that it is a possibility to have  or as your answer the following note will be included. (To enter  or , type INFINITY or INFINITY.) Note: Just because this note is included does not mean that the answer will be  or . The note simply marks any question where this is a possibility. You have found that the answer to a problem is . Enter your answer below. INFINITY [INFINITY] 4. Other Special Things (a) How much are these things worth? Each problem has a table to the left of it. If there are, for example, 5 answers required in the problem there will be 5 rows of numbers in the table. The first answer corresponds to the first row of numbers, etc. Use the table on the left to answer the questions below. How much is this answer worth? 1 [1] point(s) How much is this answer worth? 0.5 [0.5] point(s) pts 1 1/1 2 0.5/0.5 3 2/2 4 1/1 4.5/4.5 subs 1/20 1/20 2/20 2/20 Viewing: Last Response View: All Responses Notes How much is this answer worth? 2 [2] point(s) (b) Do this on paper. Sometimes there are parts of a question that WebAssign cannot grade automatically. These are things like graphing, or sketching, or working out the intermediate steps before the final solution is found. If you are asked to do these types of things the following note will be included. (Do this on paper. Your teacher may ask you to turn in this work.) In most cases your teacher will never request that you submit this work to them (they will let you know beforehand if they would like to see your work). However, it is always a good idea to complete this work fully because you might be expected to do this on a quiz or test. Why should you do any work that you are told to do "on paper"?
