P403: Statistical Methods for Psychological Research

Tentative solution is termed as :

• cause

• judgement

• hypothesis

• effect

Which method of correlation arranges the data in hierarchical order?

• Karl Pearson method

• fissure method

• Spearman rank method

• All of these

when there is an equal chances of plotting on NPC:

• When both sides of curve is having 50% cases

• When both sides of curve is having 60% cases

• When both sides of curve is having 30% cases

• When both sides of curve is having 90% cases

Shape of NPC is:

• Triangular shaped

• Rectangular shaped

• Conical shaped

• Bell shaped

Range can be calculated by:

• Multiplying Highest value and lowest value

• Adding Highest value and lowest value

• Dividing Highest value and lowest value

• Subtracting Highest value and lowest value

Negative correlation takes place:

• When both variables moves in organised manner

• When both variables moves in different manner

• When both variables moves in same direction

• When both variables moves in opposite direction

Normal distribution is symmetric about

• standard variation

• mean

• covariance

• variance

Formula of Interquartile range is :

• Q3-Q2

• Q3-Q1

• Q4-Q1

• Q4-Q2

Standard score is denoted by:

• R

• Y

• X

• Z

A measure of the spread or variability of scores in a group of people is called :

• Norms

• Reliability

• Standard Deviation

• validity
