The International Math Challenge is administered across the world for students to acquire acknowledgment for their skills in mathematics. The exam is conducted at different grade levels and brings many possibilities for students to gain recognition, rewards, certificates, and even scholarships for further studies. One of the popular Maths challenges that nurture maths intellectuals is the International Math Olympiad. It is a big platform that concedes and rewards math masterminds worldwide. Candidates from more than a hundred countries join the Olympiad challenge every year.

Overview of Maths Olympiad

International Math Challenge is an ambitious exam that evaluates students for their mathematical talents and abilities. The main objective of this test is to inculcate a fierce mindset in students all over the world. Unlike school exams, Maths Olympiad tests are deliberated to unveil the real meaning of maths education. It offers a wider sight of math subjects and their empirical applications. Students who resolve problems intellectually using the acquired skills of math undoubtedly become problem-solvers.

Importance of Math Olympiad

Math Olympiad enhances the mathematical capability and competitive skills and knowledge of students. It allows them to find out their abilities and potential. Participating in such international competitive exams provides a strong fundamental for gaining an overall academic distinction. Students who participate in International Maths Olympiad acquire the confidence to answer difficult and complex questions. This gives them mastery over their competitors. Rewards and acknowledgment gained through the Maths Olympiad exam are highly beneficial in the academic portfolio and career planning of students.

Registration for Maths Olympiad

While many Maths Olympiad tests are held and administered through the school, some let children register individually. To get more information about the registration processes, students can visit our website.

Benefits of the International Maths Olympiad

Maths Olympiad is the type of platform that is excellent for enhancing the abilities and skills of your children. Students who join in Maths Olympiad exam have demonstrated increased marks in academics too. It is like an exam of a student’s mind of earlier learned concepts.

The International Maths Olympiad is an open manifesto for all students to examine their intellectual aptitude and talents. Preparing for the Maths Olympiad test qualifies students to inspect their math abilities against their fellows at school, national, and international standards. It allows students to know where they appear regarding their mathematical skills.

Finally 

Studying and preparing for the maths Olympiad will enhance the logical reasoning and thinking abilities of students and will make them move toward strong career opportunities. If you have any confusion in the process of participating in the International Maths Olympiad Challenge, we are here to guide you at every step of your success. Click here to raise your query.

When the NBA celebrated the start of its 75th season in fall 2021, it was clear that the 3-point shot adopted by the league in 1979-80 had transformed the sport.

The number of attempts beyond the arc had increased in each of the previous 10 seasons, from 22.2% in 2010-11 to 39.2% in 2020-21, and it had been nearly five years since a team won a game without making at least one 3-pointer (that streak is now up to eight years). Led by 3-point specialists Steph Curry and Klay Thompson, the Golden State Warriors had won three of the previous seven NBA titles and were about to win a fourth in 2022.

It appeared that the 3-point revolution would never end. But a recent study by Falk College of Sport and Human Dynamics sport analytics professor Shane Sanders and associate professor Justin Ehrlich shows that while the number of 3-point shots continues to increase, the average expected value of 3-pointers has become less than 2-pointers since the 2017-18 season.

“When taking fouled shots and made free throws into consideration, we found that what had long been a premium for the 3-point shot started to become a dispremium in the 2017-18 season and that trend is continuing,” Ehrlich says. “The implication of these findings is enormous in terms of potential impact on roster construction and offensive philosophies.”

The research preprint from Sanders and Ehrlich, “Estimating NBA Team Shot Selection Efficiency from Aggregations of True, Continuous Shot Charts: A Generalized Additive Model Approach,” is available through the Social Science Research Network website. Sanders and Ehrlich will present their paper as one of seven finalists in the research competition at the NBA-centric MIT Sloan Sports Analytics Conference March 1-2 in Boston, Massachusetts.

“In past conferences, there has been a lot of discussion among NBA executives about how basketball analytics created the 3-point ‘moneyball’ era of basketball and how this has impacted the popularity of the game,” Sanders says. “Perhaps ironically, our research uses basketball analytics, along with a fully specified team offensive objective function, to say there is now too much 3-point shooting for a point-maximizing offense.”

To conduct their research, Sanders and Ehrlich developed a new shot chart that uses a generalized additive model to estimate total shot proficiency continuously in the half-court. Their shot chart incorporates missed shots that draw a shooting foul—and shot-pursuant free throw scoring—to determine total scoring yield following a shot decision.

Current expected value formulas fall short by not including this additional information, which, when combined with the outcome of the initial shot attempt, results in what Sanders and Ehrlich call the “true point value” of a shot. For the 2022-23 NBA season:

• True Value from 2-point shot attempts=1.181
• True Value from 3-point shot attempts=1.094

And even when not factoring in free throws, the researchers found that the expected value from 3-point shots are now worth less than 2-point shots. For the 2022-23 NBA season:

• Expected value from 2P field goal attempt=2P% * 2 = .548 * 2= 1.096
• Expected value from 3P field goal attempt=3P% * 3 = .361 * 3= 1.083

The true value data can be found in this dashboard, and the graph above shows the expected and true values of 2- and 3-point shots from 2016-22.

According to this research, the expected value from average 2-point field goal attempts (FGA) is now worth 0.013 points more than average 3-point FGA, even before factoring in shot-pursuant free throw scoring. In other words, if you multiply the probability of making a 3-point FGA times the value of a 3-point FGA, it’s worth less than if you multiple a 2-point FGA times the value of a 2-point FGA.

When discussing true point value, the researchers use the term “shot attempts” instead of “field goal attempts” because their formula includes missed shots when a player is fouled, which is not included in standard field-goal attempt statistics. So, when including made and missed free throws, the disparity based on this new true value metric is even greater as average 2-point shot attempts are now worth 0.087 more points than 3-point shot attempts.

Officials from NBA teams and the league have discussed moving the 3-point line back from its current distance of 23 feet, 9 inches (22 feet in the corners). But as this study shows, the value of a 3-pointer is decreasing at the current distance, and teams are already starting to alter their shot selection to emphasize more high-percentage 2-point shots.

“These research findings do not coincide completely with the unresearched musings of NBA analysts Charles Barkley and Shaquille O’Neal,” Sanders says.

“For example, our findings do not suggest that such perimeter stars as Stephen Curry or Damian Lillard should not shoot a lot of threes. It means marginal stretch fours and other marginal outside shooters should not pull up for a 3 as often and that some marginal outside shooters should not extend their range to 25-26 feet or more. Players can still achieve the offensive spacing benefits of positioning on the perimeter without some players shooting from there quite as often.”
