DESCRIBING DISTRIBUTION

Question 1

What are the four ways to describe the distribution?

Answer 1

1. Frequency distribution
2. Frequency polygon
3. Measures of variability
4. Standardized scores

Question 2

What is Frequency distribution?

Answer 2

It is tabulation of scores. It is used to show how frequent the scores will fall in range of values. The distribution can also be ascending or descending.

Question 3

What is Frequency polygon?

Answer 3

Question 4

It is the measurement of symmetry of distribution

Answer 4

Skewness

Question 5

What are the two kinds/types of skewness?

Answer 5

Positive skewness and negative skewness

Question 6

It is the right shaped

Answer 6

Positive skewness

Question 7

It is left shaped

Answer 7

Negative skewness

Question 8

It tells about if the tailed is heavy or light

Answer 8

Kurtosis

Question 9

What are the three kinds of kurosis?

Answer 9

Platykurtic, Leptokurtic and Mesokurtic

Question 10

Answer 10

Platykurtic

Question 11

Peak type of kurtosis

Answer 11

Leptokurtic

Question 12

It is the normal kurtosis

Answer 12

Mesokurtic

Question 13

What are the three measures of central tendency?

Answer 13

Mean, median and mode

Question 14

It is the average of scores

Answer 14

Mean

Question 15

It is the half score or 50% of the score

Answer 15

Median

Question 16

It is the repetitive scores in a set

Answer 16

Mode

Question 17

What are the three measures of variability?

Answer 17

Range, Quartile Deviation, Standard Deviation

Question 18

It is the difference of two extreme Highest minus lowest

Answer 18

Range

Question 19

It measures the spread or dispersion

Answer 19

Quartile Deviation (semi -interquartile range)

Question 20

Formula of quartile deviation

Answer 20

Q3 - Q1/2

Question 21

It is the square root of variance

Answer 21

Standard deviation

Question 22

If the SD is O it means

Answer 22

It same with the mean

Question 23

If the SD is greater than 0

Answer 23

It means mas okay

Question 24

If the SD is less than 0

Answer 24

It means masyadong malapit sa mean

Question 25

What are the three types of standardized scores?

Answer 25

Individual score, Linear standard score and normalized standard scores

Question 26

It is under the individual score which is the percentage of the below interest score

Answer 26

Percentile score/rank

Question 27

What are the two types of linear standard scores?

Answer 27

Z scores and T scores

Question 28

It is under the linear standard score which is a deviation of the score from the mean in a standard deviation units

Answer 28

Z scores

Question 29

It is normalized standardized scores which has SD of 10 and mean of 50

Answer 29

T scores
