MAT 101 MIDTERM TEST QUESTIONS WITH 100%
ACCURATE SOLUTIONS
DESCRIPTIVE
Branch of statistics that deals with data analysis and one of its technique is to "describe" data in
symbolic form and abbreviated fashion.
INFERENTIAL
Branch of statistics that has the ability to "infer" and to generalize. It is also the right tool to
predict values that are not really known.
NOMINAL SCALE
What kind of scale is shown on 1-Male ; 2-Female
MEDIAN
The middle point or midpoint of any distributions. It separates the upper half from the lower
half of distribution.
PERCENTILE
The _______ are the score-points that divide a distribution into 100 equal parts
QUARTILE
The ________ are the points that divide a distribution into four equal parts.
NORMAL DISTRIBUTION
Is a continuous, symmetric, bell-shaped distribution of a variable.
MEAN, MEDIAN, AND MODE
The ______, ______ and _________are located at the center of a normal distribution
POSITIVE CORRELATION
, "As x increases, y increases" is what type of correlation ______________________
NEGATIVE CORRELATION
"As x increases, y decreases" is what type of correlation _____________________
MEASUREMENT
It is an essential quantifying an observation according to a certain rule. It is also assigning
numbers in a prescribed way. _______________
ORDINAL
If the data are labelled 1st, 2nd, 3rd, and so on, in what kind of scale does it falls
RANGE, VARIANCE, AND STANDARD DEVIATION
These three measures can provide the information about spread of the scores in the
distribution
64
The following is a list of retirement ages for the workers in production plant: 65, 64, 65, 61, 62,
64, 65, 63, 63, 65, 64. What is the median
55
Mean is the arithmetic average of all scores. In the data: 34, 56, 75, 43, and 67, what is the
mean?
75%
The third quartile Q3 is on what percentile rank?
5TH DECILE/ 2ND QUARTILE/ 5TH PERCENTILE
The median score is also the?
10.5TH
If a data set consists of 20 scores, which position is the median
