Answer:
B). A Cross-sectional research design.
Explanation:
A cross-sectional research design is demonstrated as a kind of observation study that involves the study and analysis of a representative subset from the population at a particular point of time.
In the given example, Tucker is employing 'cross-sectional research design' as he selects a representative subset('a group of 5-year-olds, a group of 10-year-olds, and a group of 15-year old) from the population at the same time for study and analysis(by interviewing them) . This implies that Tucker adopts a '<u>cross-sectional research design</u>.'
I don't know how this is a question, but it is correct.
People who were scared a strong central government and total control (like the experience with Britain), wanted to give states power to counteract the effect. It made people like Thomas Jefferson feel assured that the U.S. would stay a democracy.
If there are especially few frequencies on the left cease of the abscissa on a frequency polygon when compared to the right quit, the curve is: Negatively skewed.
Definition: Frequency is the measurement of the number of instances that a repeated occasion happens in line with a unit of time. The frequency of wave-like patterns together with sound, electromagnetic waves (which include radio or light), electric signals, or other waves, expresses the range of cycles of the repetitive waveform in line with the second.
The time period frequency refers back to the variety of waves that pass a hard and fast point in unit time. It also describes the wide variety of cycles or vibrations passed through at some stage in one unit of time by a body in periodic movement.
Frequency is a crucial parameter used in technological know-how and engineering to specify the temporal price of exchange determined in oscillatory and periodic phenomena, together with mechanical vibrations, audio signals (sound), radio waves, and light.
Although the standard definition of frequency is based on occasions in keeping with 2d, different units of time may be used, consisting of minutes or hours. for instance, a human heart may beat at a frequency of sixty-eight beats according to the minute. A 78 report on a turntable turns at a charge of 78 revolutions according to a minute or seventy-eight rpm.
