4TH 10

Question 1

the distribution when extreme observations are found on the right or left end of the distribution,
distribution is BLANK if it departs from symmetry

Answer 1

SKEWED

Question 2

BLANK measure the flatness of the distribution

BLANK - sharp top
BLANK - flat top
BLANK – not so sharp not so flat

Answer 2

KURTOSIS

leptokurtic

platykurtic

Mesokurtic

Question 3

a numerical value that summarizes a set of observations into a single value, and that value may be used to represent the entire population

Answer 3

Measure of Central Location

Question 4

Measures of Central Location

Answer 4

Arithmetic mean
(or mean)
Median
Mode

Question 5

THE MOST POPULAR MEASURE OF CENTRAL TENDENCY

Answer 5

MEAN

Question 6

middle value of a set of observations arranged in an increasing or decreasing order of magnitude

Answer 6

MEDIAN

Question 7

value or values which occur the most number of times, or the value or values with the greatest frequency

Answer 7

MODE

Question 8

a numerical value computed from the given observations measures how the data spreads from the CENTRAL LOCATION
the LESSER the MEASURE is, the CLOSER the values of the observations from the central value

Answer 8

Measures of Variability

Question 9

measures of location that describe or locate the non-central position of a set of data
also known as BLANK

Answer 9

FRACTILES
quantiles

Question 10

has the same properties as the variance except the last one. Its unit of measure is the same as that of the observations in a set of data.

Answer 10

standard deviation
