... of the population may be identified and removed at this point. This may also help identify variables that have distributions that depart from the normal distribution and require special handling. The next step is the calculation of descriptive statistics for each variable. The most common statistics are measures...

..., the typical method for reporting scores on conceptual tests is the normalized gain (〈 g〉), which is a rough measure of a course's average effectiveness in promoting conceptual understanding ( Hake, 1998 ). The normalized gain is generally defined as “the amount students learned divided by the amount...

... is normally used to convert the DC to the alternating current (AC) for residential usage ( Energy Education ). FIG. 7.3 The working mechanism of a PV cell ( Electrical A2Z ). Costs The main cost attributed to the solar PV system is the capital cost and the cost of energy produced by the system over its...

... the plotted P-V curve). The calculated PV power by the model is then compared with the one measured. The normal operation limits are defined as follows ( Mellit and Kalogirou, 2022b ): (6.3) U p p e r = μ + 3 σ (6.4) L o w e r = μ − 3 σ where µ and σ are the mean...

... energy systems. Wang et al. (2012) proposed time- and energy-based indices, respectively, determined by considering the total available time, time of reduced output, and outage time and by normalizing the expected output energy to the ideal output energy. The results of their analysis...

... function is to obtain functions that are easier to solve; however, each segment normally needs binary variables that can drastically increase the CPU time. Additionally, Dehghani et al. (2018) proposed a hybrid robust scenario-based optimization model to design a photovoltaic supply chain under...

... unit load [see Fig. 1.1(c) ]. Market price. Exogenous uncertainties normally occur throughout the entire project caused by market variabilities such as product prices, drilling costs, utility prices, and significantly increases the complexity of uncertainty in practice ( Grossmann et al...

... , instructors can empower students and strengthen their defenses by creating an inclusive and equitable learning environment. With proper coaching, all students can have a high sense of belonging, be unafraid to struggle and fail, and recognize that failures are normal and should be embraced since...

..., such as analyzing the video-recorded motion of a ball. Preliminary assessments of Studio Physics were promising, with students reporting positive experiences and giving positive course evaluations. However, an assessment of the implementation showed normalized gain of only 0.22 on the FCI, which is no better than...

... systemic injustices baked into science education. Work within this approach presents affect not simply as a co-equal learning goal with conceptual or epistemological progress but rather as a way to reimagine goals of science education, to empower learners and to interrogate normalized ideas around who can...
