Hypothesis
The research focuses on the relationship between grit – “perseverance and passion for long-term goals” and the educational achievement, in comparison with other factors like personalities (Rimfeld, Dale, Kovas and Plomin, 2016, p. 780). The hypothesis of the research is that grit is a significant prediction of academic achievement. The researchers also want to understand more about the etiology of grit, its genetic and environmental origins. They want to know why individuals differ in grit and why the way they develop their grits are different (Rimfeld, Dale, Kovas and Plomin, 2016).
According to Duckworth, a math teacher in middle school and high school, grit can be important as intelligence and can play a more significant role …show more content…
The study used a high selected sample called Twins Early Development Study (TEDS) sample which presents the U.K. population. All children having serious medical or psychiatric problems were excluded from the analysis of the research. Both of same-sex and opposite0sex twin pairs were included in the research (Rimfeld, Dale, Kovas and Plomin, 2016). …show more content…
In phenotypic analyses, the researchers compared the means and variance for monozygotic (MZ) pairs and dizygotic (DZ) twins and for boys and girls. Monozygotic twins shared 100% of their genes while dizygotic twins shared 50% of their genes. The study used univariate analysis of variance (ANOVA) to test the interaction between age and sex and their mean differences. The relationship between the two subscales of Grit-S (perseverance of effort and consistency of interest), the Five Factor model and GCSE grades was assessed using correlation. Multiple regression was used to estimate the prediction of Grit-S scores over GCSE grades. The researchers randomly selected one twin per pair for all phenotypic analyses to keep the independence of the data (Rimfeld, Dale, Kovas and Plomin, 2016 p.
