Are you bad at math? Don't be so sure

NEW DELHI: Here is some good news for students who think they are bad at math: you may be wrong. A study has found that about 20 percent of people who claim they are not good at math actually perform well and score in the top half of those taking a math test.

But there is some bad news too: one-third of people who say they are good at math actually score in the bottom half.

"Some people mis-categorize themselves. They really don't know how good they are when faced with a traditional math test," said Ellen Peters, co-author of the study and professor of psychology at The Ohio State University.

The results are important because they suggest that being "good at math" isn't a single concept, Peters said.

Peters conducted the study with Par Bjalkebring, a visiting scholar from the University of Gothenburg. It was published in a recent issue of the Journal of Personal and Social Psychology.

Those people who think they're good at math - even when their scores on math tests don't show it - have a numeric competency that may be helpful in some real-life situations.

People who were low in subjective numeracy were more likely to simply skip questions instead in the same math task.

"They just stop giving responses. We don't know why. It could be a lack of confidence with numbers, or they are just not motivated," said Peters, who is also director of the Behavioral Decision Making Initiative at Ohio State.

"This has important implications for everyday life. People who are low in subjective numeracy may not do their taxes on time or they may not make thoughtful choices on their health insurance because they just give up when faced with a lot of numbers."

The study involved 130 people recruited at a university to take part in a four-day study. The study examined three different types of numeric competency.

One is objective numeracy, which is what most people think of when they think of "being good at math." This is the ability to work with numbers and score well on traditional math tests. This was measured with a test that asked questions like "If the chance of getting a disease is 10 percent, how many people would be expected to get the disease out of 1000?"

The second was subjective numeracy, which is people's self-reports on their ability and preference to work with numbers. This was measured by asking people to answer questions like "How good are you at working with percentages?" and "How often do you find numerical information to be useful?"

The third is symbolic-number mapping, which is the ability of some people to estimate numeric magnitudes quickly in their head and map them to a number line. This was measured by giving participants a line drawn on a piece of paper that they were told began at zero and ended at 1,000. They were asked to indicate where on the line various numbers (4, 6, 18, 71, 230 and 780) would be located. Peters said this may be what would allow a carpenter, for example, to quickly estimate how much wood he would need to put in a hardwood floor in a complex room with intricate corners.

The results showed that people approached each problem through their combined strengths and weaknesses on each of the three types of numeric competency studied.

Overall, Peters said the results suggest that there may be more than one way for people to be successful at math and at using numbers important to their everyday decisions.

For example, people who are good at objective numeracy probably have no problems keeping track of their credit card spending because they may find it easy to keep a running list of purchase amounts. Those who are better at symbolic-number mapping may not keep detailed records, but they may be good at roughly estimating their credit card purchases so they don't spend too much.

"Some of the ways we can be good at numbers can compensate for other ways that we're bad at numbers," Peters said. "That may not work for everyone in every situation, but there is more than one way to be good at math."
