Gender Gaps In Mathematics And Reading
The gender gaps in mathematics and reading achievement refer to the finding that, on average, boys and girls perform differently in mathematics and reading skills on tests. On average, boys and men score somewhat better in mathematics, while girls and women score somewhat better in reading skills. Mathematics and reading gaps by country The Programme for International Student Assessment assesses the performance of 15-year-olds in mathematics and reading in OECD and OECD partner countries. The table below lists the scores of the PISA 2009 assessment in mathematics and reading by country, as well as the difference between girls and boys. Gaps in bold font mean that the gender gap is statistically significant ( p<0.05). A positive mathematics gap means that boys outperform girls, while a negative mathematics gap means that girls outperform boys. A positive reading gap means that girls outperform boys (this is true in every country, so no country has a negative reading gap). There is ...

Programme For International Student Assessment
The Programme for International Student Assessment (PISA) is a worldwide study by the Organisation for Economic Co-operation and Development (OECD) in member and non-member nations intended to evaluate educational systems by measuring 15-year-old school pupils' scholastic performance on mathematics, science, and reading. It was first performed in 2000 and then repeated every three years. Its aim is to provide comparable data with a view to enabling countries to improve their education policies and outcomes. It measures problem solving and cognition. The results of the 2022 data collection were released in December 2023. Influence and impact PISA, and similar international standardised assessments of educational attainment are increasingly used in the process of education policymaking at both national and international levels. PISA was conceived to set in a wider context the information provided by national monitoring of education system performance through regular assessment ...

Statistical Significance
In statistical hypothesis testing, a result has statistical significance when a result at least as "extreme" would be very infrequent if the null hypothesis were true. More precisely, a study's defined significance level, denoted by \alpha, is the probability of the study rejecting the null hypothesis, given that the null hypothesis is true; and the p-value, ''p''-value of a result, ''p'', is the probability of obtaining a result at least as extreme, given that the null hypothesis is true. The result is said to be ''statistically significant'', by the standards of the study, when p \le \alpha. The significance level for a study is chosen before data collection, and is typically set to 5% or much lower—depending on the field of study. In any experiment or Observational study, observation that involves drawing a Sampling (statistics), sample from a Statistical population, population, there is always the possibility that an observed effect would have occurred due to sampling error al ...

P Value
In null-hypothesis significance testing, the ''p''-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct. A very small ''p''-value means that such an extreme observed outcome would be very unlikely ''under the null hypothesis''. Even though reporting ''p''-values of statistical tests is common practice in academic publications of many quantitative fields, misinterpretation and misuse of p-values is widespread and has been a major topic in mathematics and metascience. In 2016, the American Statistical Association (ASA) made a formal statement that "''p''-values do not measure the probability that the studied hypothesis is true, or the probability that the data were produced by random chance alone" and that "a ''p''-value, or statistical significance, does not measure the size of an effect or the importance of a result" or "evidence regarding a model or hypothesis". That ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Correlation And Dependence
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are '' linearly'' related. Familiar examples of dependent phenomena include the correlation between the height of parents and their offspring, and the correlation between the price of a good and the quantity the consumers are willing to purchase, as it is depicted in the demand curve. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example, there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling. However, in gen ...

Gender Equality
Gender equality, also known as sexual equality, gender egalitarianism, or equality of the sexes, is the state of equal ease of access to resources and opportunities regardless of gender, including economic participation and decision-making, and the state of valuing different behaviors, aspirations, and needs equally, also regardless of gender. UNICEF (an agency of the United Nations) defines gender equality as "women and men, and girls and boys, enjoy the same rights, resources, opportunities and protections. It does not require that girls and boys, or women and men, be the same, or that they be treated exactly alike."The ILO similarly defines gender equality as "the enjoyment of equal rights, opportunities and treatment by men and women and by boys and girls in all spheres of life" gender equality is the fifth of seventeen Sustainable Development Goals, sustainable development goals (Sustainable Development Goal 5, SDG 5) of the United Nations; gender equality has not incorp ...
