For comparison, quantitative data, in this case, could be the frequency of workers to belong to those ethnicities and races. Often, expressions work consistently for closely connected values but won’t work at all for rare or special values, such as 0, negative numbers, and fractions. Quantitative comparison, or QC, is a new question type that the GRE throws at you. Because Quantitative Comparison questions are such a large part of Quant, it’s important you give ample attention to these types of questions in your study sessions. Plug in the right numbers based on given conditions. Let’s say their distances from the power station are 14, 13, and 12.5 miles, respectively. And this guide will help you do exactly that. Now, it’s time to plug in some numbers. Quantitative Comparison questions account for more than a third of GRE Quant. Let’s say $x=1$ and apply this scenario to both of our quantities: In this case, Quantity A (3) is larger than Quantity B (1). Quantitative Research: Quantitative research uncovers measurable data to formulate theories and facts and uncover patterns. Looking for more Quant resources? Immunohistochemical (IHC) assays performed on formalin-fixed paraffin-embedded (FFPE) tissue sections traditionally have been semi-quantified by pathologist visual scoring of staining. Both of these numbers are larger than 1, so the correct choice is A: Quantity A is greater. If you’re able to put these strategies into practice, and if you do enough practice, you can be sure to ace any quantitative comparison question on the GRE. But the answer choices above are the same answer choices for all Quantitative Comparison questions, regardless of the type of math they’re testing. The Factor Comparison Method - This method is a combination of the ranking and point system. Keep it up, Your email address will not be published. Research Methodologies: A Comparison of Quantitative, Qualitative and Mixed Methods Published on December 16, 2016 December 16, 2016 • … Try our 5-day full access trial for free: In this question, we’re being asked to compare the slope of line k to Quantity B (1). Also, be extra vigilant when selecting the answer choice D, which says “The relationship cannot be determined from the information given.” Do not choose D as the right answer, if it is clear that the values of the two quantities can be determined by computation. This may seem pretty basic right now, but it’s easy to miss when you’re under pressure. Some of the harder questions may take more than 90 seconds to solve, but if you practice them enough, you’ll be able to get it down to 60 seconds. But then there are a few numbers that you should definitely prefer over the rest, because these numbers are proven to make the whole process easier and faster. So there’s no need to worry about any sudden changes or curve balls. For example, if you can’t recall the circumference formula, you’ll be unable to solve a Quantitative Comparison asking you to compare the circumferences of two separate circles. It is hence important that you understand how this question type works, and learn the techniques required to solve such questions quickly and easily. Which is why it is safe to say that you’re able to get a good grip on this question type, then it’s safe to say that almost half of the battle is won. Download it for free now: Hannah graduated summa cum laude from the University of Southern California with a bachelor’s degree in English and East Asian languages and cultures. Sign up for PrepScholar GRE updates by email. This type of analysis is more concerned with how and why instead of what, where and when which are more focused upon when conducting quantitative research. Remember that in some cases, you need to check two contradictory results to make sure the answer is not C or D. So, you should keep this limitation in mind before going ahead with the strategy. Another step to take before attempting to solve a Quantitative Comparison is to determine whether there are any rules or formulas you’ll need in order to solve the problem. A popular method for solving algebraic expressions in Quantitative Comparison questions is plugging in numbers. Approximation is easily the most important technique that you need in your arsenal when solving QC questions. In general, the qualitative data analysis has the following steps: Step 1: Become familiar with your data. Here’s a more detailed point-by-point comparison between the two types of research: 1. The answers received for these quantitative survey questions are analyzed and a research report is generated on the basis of this quantitative … Why just positive numbers in these two cases? It’s totally up to you. Our top tips for approaching a Quantitative Comparison on the GRE are to: When it comes to studying for Quantitative Comparison questions, be sure you: Hopefully, you now have a little more confidence when it comes to tackling Quantitative Comparison questions on the GRE! Like cases are treated alike, and different … Which means, a triangle that looks like a right angled triangle is not, unless explicitly mentioned in the question stem. Not sure what to study? We give you minute by minute guide.

Quantitative Survey Questions: Definition. In this type of question, the test taker has to compare two quantities A and B and determine a relationship between which of the two is larger. Also get Free GRE tips directly in your inbox! On the GRE, you will definitely come across QC questions that are hard to grasp. When $x=1$ Quantity A is greater than Quantity B, but when $x=-1$ the two quantities are equal. You don't NEED a prep program to get a great GRE score. Quantitative Comparison questions test our ability to (quickly) analyze some information and figure out how to quantities compare to each other. Because we aren’t given an exact value for x, let’s try plugging in a combination of positive and negative numbers to see how they affect the quantities. If you see that Quantity A is greater than Quantity B in one case and Quantity B is greater than Quantity A in another case, choose “The relationship cannot be determined from the information given.”. Typically, geometry questions contain diagrams of shapes; algebra questions contain equations and inequalities; and data analysis questions contain tables and graphs. Now, let’s choose a couple of possible locations for our stations. Although a bit of calculation wouldn’t hurt and may in fact help confirm the right answer, but if you’re doing a lot of number crunching on test day, you’ll run the risk of probably overlooking whatever math concept is at the heart of the question. In the end, Quantity A simplifies to $x^9$ and Quantity B also simplifies to $x^9$. So, let us check with 1. The ETS does not endorse, nor is it affiliated in any way with the owner or any content of this site. The general method of comparing things is the same for comparative research as it is in our everyday practice of comparison. For example, it is possible to discover exactly how many times per second a hummingbird's wings beat and measure the corresponding effects on its … Below is the same coordinate system marked with one-point increments to help us make a more precise estimate: According to our estimates, our line has possible points around (2, 4) and (3, 5). So, divide the two quantities by 2 first, and you’ll get: Now, if you look again, you can see that x 2 + 2 is common between both the quantities, so you can subtract them both and see what happens. You can think of C as being short for “congruent,” meaning “the same.” And you can associate D with the word “determined” to remind you that D “cannot be determined.”. Quantitative and qualitative research use different research methodsto collect and analyze data, and they allow you to answer different kinds of research questions. Quantitative Comparison questions account for more than a third of GRE Quant. You can work with either of these estimated sets of coordinates. The red dot is the power station, and the three blue dots are the substations: In this example, all three substations are around 14 miles away from the power station (their distances are slightly less than 14 as they cannot be placed directly on the corner). To illustrate this idea more clearly, take a look at the following example: Because of the presence of a histogram, we can immediately recognize this problem as a data analysis question — specifically, one testing us on our knowledge of standard deviations and distribution. We have another x to multiply this expression by — meaning, all we have to do is add 1 to the current exponent. Whenever you are faced with a tough problem that involves a lot of variables, you can simplify it by just substituting the variables in the given quantities with small numbers. Thus, in order to compare the two quantities, we must know how to find a slope using the slope formula. But let’s try another arrangement before choosing an answer choice.
