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..

Write the radian measure of an angle with 9 clockwise rotations in standard position. => 18 π or - 18 π or - 9 π or 9 π..

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

Angles that are formed by counter clockwise (anti clockwise) rotation, such as the one shown in fig (ii) are said to be positive or to have positive measure. Angles that are formed by a clockwise rotation, like the one in fig(iii) are said to be negative or to have ne..

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..

Which of the following statement(s) is/are true ? I. Mode is the measure of central tendency used in exploratory data analysis (EDA). II. Extremely low data value in the data set can be considered as an outlier. III. Percentiles are the same as percentages. => II only or I, II a..

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..

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) at t = 0. For the sake of convenience, both distance and time are ..

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..

Measurement of Length - 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 b..
