measuring position: percentiles

Recognize the incorrect statement(s). I. When all data for a variable are transformed into z scores, the resulting distribution will have a mean of 1 and a standard deviation of 0. II. The z score represents the number of standard deviations that a data value falls above or below the mean. III. Per..

Give the radian measure of an angle with 2 clockwise revolutions in standard position. => π or - 4 π or 4 π or 2 π..

If an angle of any measure be given, one can always construct (or draw) a cartesian co-ordinate reference frame in such a way that the origin is at the vertex of the angle, and positive half of the x axis coincides with the initial side of the angle. When this has been achieved..

Position-Time Relations using Position-Time Graphs - In this section, Let us understand how the position changes with time when the velocity changes uniformly with time. Let us consider a particle moving with uniform acceleration 'a' and having an initial velocity v (0..

Which of the following statement(s) is/are true? I. If a student secured 75th percentile in an exam, then it means that he scored 75 out of 100. II. A statistic that tells the number of standard deviations a data value is above or below the mean is called z score. III. The distribution is..

Different types of lengths are measured by using different types of instruments. Lengths like the length of cloth or length of a line can be measured by using measuring tape, a metre scale or a foot rule. But these instruments cannot be used to measure the di..

Dipole Moment - A Measure of Degree of Polarity - Molecules having two equal and opposite charges separated by certain distance are said to possess an electric dipole. In the case of such polar molecules, the centre of negative charge does not coincide with the centre of positive..

Give the degree measure of an angle with 1 6 clockwise revolution in standard position. => 60 o or 15 o or - 15 o or - 60 o..

Write the degree measure of an angle with 3 6 5 counterclockwise revolution in standard position. => 1080 o or 756 o or 1512 o or 432 o..

Give the degree measure of an angle with 1 4 3 counterclockwise revolution in standard position. => 840 o or 420 o or 630 o or 210 o..
