Why is Nhst bad? NHST is unsuitable for large datasets Most NHST studies rely on nil null hypothesis testing (Nickerson, 2000) which means that H0 expects a true mean difference of exactly zero between conditions with some variation around this true zero mean. The p-value is smaller if the test statistic is larger. Why is […]
What are the benefits of subject design?
What are the benefits of subject design? The main advantage that the within subject design has over the between subject design is that it requires fewer participants, making the process much more streamlined and less resource heavy. For example, if you want to test four conditions, using four groups of 30 participants is unwieldy and […]
What temperature should I wash white bed sheets on?
What temperature should I wash white bed sheets on? Use the hottest water setting on your washing machine that’s safe for the material. Polyester blends are best washed using warm water, while cotton can tolerate hot water. Hotter water kills the most germs and takes care of dust mites that thrive in bedding. How long […]
Is pcl5 an ionic compound?
Is pcl5 an ionic compound? Phosphorus pentachloride Is PCl5 both ionic and covalent? PCl5 is a covalent in gaseous and liquid states but ionic in solid state. Is MoCl6 ionic compound? The result is an electron-pair sharing bond which looks a lot like a covalent bond between Mo & Cl with one electron from Mo […]
Does all the ice melt calorimetry?
Does all the ice melt calorimetry? Once all the ice has melted, the temperature of the liquid water rises, absorbing heat at a new constant rate. At 100oC the water begins to boil….Heat and Change in Physical State. Substance Mercury Melting Point (oC) –38.9 ΔHfus, (J/g) 11.8 Boiling Point (oC) 357 ΔHvap (J/g) 272 When […]
What is one of the most important developmental tasks in late adulthood?
What is one of the most important developmental tasks in late adulthood? Newman and Newman (2012) identify developmental tasks as areas of learning for most people in modern society. They associate the stage of later adulthood (60 to 75) with such tasks as accepting one’s life, redirecting energy toward new roles, promoting intellectual vigor and […]
Is the Carnot cycle 100% efficient?
Is the Carnot cycle 100% efficient? No,, never . It can be 100℅ only if the sink temperature is zero or the source temperature is infinite (very large value). Carnot is an ideal cycle is provides benchmark to compare efficiency of other cycles. Carnot efficiency is the maximum efficiency that can be achieved in a […]
What are the methods of measuring resistance?
What are the methods of measuring resistance? Measurement of Medium Resistance (1Ω – 100kΩ) Ammeter-Voltmeter Method. Wheatstone Bridge Method. Substitution Method. Carey- Foster Bridge Method. Ohmmeter Method. Which method is used for high resistance? Two methods are used to measure high resistance, the constant voltage method and the constant current method. In the constant- voltage […]
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge?
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge? Two identical capacitors are connected as shown in the figure. A dielectric slab is introduced between the plates of one of the capacitors so […]
Can an explosion trigger an earthquake?
Can an explosion trigger an earthquake? A nuclear explosion can cause an earthquake and even an aftershock sequence. However, earthquakes induced by explosions have been much smaller than the explosion, and the aftershock sequence produces fewer and smaller aftershocks than a similar size earthquake. Not all explosions have caused earthquakes. Can a nuke cause a […]
