(a) 16. States that the absence of a difference or relationship, always hoped to be rejected.
(a) 17.It is usually called the research hypothesis, which states the presence of a
difference or relationship.
(a) 18.An alternative hypothesis where the direction of difference or relationship
is not specified.
(a) 19 The rank for unrepeated score
(a) 20.An alternative hypothesis is if there is difference , the group has a higher/lower value, if there is relationship , then the relationship is either positive or negative
(a) 21.A statistical test used if Ha uses the less than (“ <“ ) symbol .The area of rejection is on the left side of the probability distribution.
(a) 22.A statistical test used if Ha uses the greater than (“> “ ) symbol .The area of rejection is on the right side of the probability distribution.
(a) 23. A statistical test used if Ha uses the not equal to “ = “ symbol. The area of rejection are on the extreme ends of the probability distribution.
(a) 24. This is also called alpha( α ) ; it is the probability of making a Type I error which is
the rejecting Ho when it is actually true.

31.The measure of the mean absolute deviation shows the absolute distance from the mean of
the given score or value in the distribution
True
False
32.Average deviation will decrease its value as the distribution becomes more heterogeneous and
the deviations from the mean increases also
True
False
33.Standard deviation becomes meaningful when it is described together with the mean
True
False
34.Standard deviation is considered as the slight reliable and important measure of spread
because it is affected by the value of each observation.
True
False
35.The absolute value of - 5 is 5

37.The standard normal distribution has a mean of 0 and a standard deviation of 1
True
False
38.The normal distribution does actually exist. Normal distribution is not a mathematical model which can not be used to represent data collected in behavioural or social science research but rather a fact of nature
True
False

model of many natural .

always hoped to be accepted .
