Q. Define Period, Amplitude and Phase Shift?
Ans.
Period, amplitude and phase shift are used when describing a sinusoidal curve
The period of a function is the smallest number p for which f( x + p) = f(x) for each x for which is defined.
The function sin(x) repeats every degrees, sin (x +) = sin(x). It is also clear by the graph that 2p is the smallest number for which this is true. The period of sin(x) is 2Π.
The amplitude of a sinusoidal wave is the distance from the central axis (the x-axis in this case) and the maximum or minimum value of the wave.
The phase shift of a curve is the shift, left or right, of the base curve.
Find out the next number in the subsequent pattern. 320, 160, 80, 40, . . . Each number is divided by 2 to find out the next number; 40 ÷ 2 = 20. Twenty is the next number.
Q. Determine Z-scores and Percentiles? Ans. Z-scores help measure how far a piece of data is from the mean. More specifically, Z-scores tell how far a piece of data is fr
