How do you know if its descriptive or inferential? Descriptive statistics describes data (for example, a chart or graph) and inferential statistics allows you to make predictions (“inferences”) from that data. With inferential statistics, you take data from samples and make generalizations about a population. What is an example of descriptive statistics in a research […]
How do we use biochemistry in everyday life?
How do we use biochemistry in everyday life? Similarly, biochemistry in general deals with body substance like enzymes, carbohydrates, amino acids, fats, proteins, hormones, DNA, RNA, pigments, etc. It is used in clinical diagnosis, manufacturing of various biological products, treatment of diseases, in nutrition, agriculture, etc. What is biochemistry and its importance? Biochemistry is both […]
What causes current to flow?
What causes current to flow? In electrical conductors, current (flow) results from the movement of electrons from one atom to the next. Negative electrons are attracted to positive electrons. At the atomic level, a negative electron will jump from one atom to another. What is a closed path for current flow called? A closed path […]
What is the tech behind self-driving cars?
What is the tech behind self-driving cars? Self-driving vehicles employ a wide range of technologies like radar, cameras, ultrasound, and radio antennas to navigate safely on our roads. What are the dangers of a self-driving car? Here are 3 dangers we should anticipate from the rise of self-driving cars: Road Accidents. Self-driving cars will have […]
Is ruby laser pulsed or continuous?
Is ruby laser pulsed or continuous? Although it lases at the standard deep-red 694.3 nm wavelength, it is both diode-pumped (making it very stable and efficient) and continuous-wave (opening up many uses not available to pulsed ruby lasers). What is pulsed mode? (C) The resulting voltage pulse that is developed across the circuit of (A) […]
What is the thickness of the foil?
What is the thickness of the foil? Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. What is used for measuring the thickness of sheet? Some characterizations of thickness gauges […]
What is evaporation process?
What is evaporation process? Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. What is effect of evaporation? The water level will decrease as it is exposed […]
Is short wave AM or FM?
Is short wave AM or FM? Shortwave (SW) radio operates on the frequencies between the AM and FM bands. Shortwave has the unique characteristic of traveling very long distances making it a powerful medium to reach the masses from even one transmitter. Is WWV still broadcasting? In the ’70s, the WWV audio signal was made […]
What is the major difference between descriptive and experimental research?
What is the major difference between descriptive and experimental research? Descriptive research refers to research which describes a phenomenon or else a group under study. Experimental research refers to research where the researcher manipulates the variable to come to an conclusion or finding. What is an example of a descriptive experiment? To experiment is defined […]
