Lesson 4 Measures of location

Question 1

are numerical description measures which indicate or locate the center of a distribution

Answer 1

measures of central tendency

Question 2

In layman’s term, a measure of central tendency is an

Answer 2

average

Question 3

commonly used measures of central tendency

Answer 3

MEAN / MEDIAN / MODE

Question 4

a set of values or measurement is the sum of all the measurements divided by the number of measurements in the set.

Answer 4

MEAN

Question 5

The mean is the most popular and widely used. It is sometimes called the

Answer 5

arithmetic mean

Question 6

characteristics of the mean

Answer 6

1. most appropriate measure of central tendency (interval or ratio)
2. lies between the largest and smallest values or measurements
3. only one value for the mean for a given set of values or measurements
4. easily influenced by extreme values

Question 7

To find the mean of a set of values wherein each value or measurement has a different weight or degree of importance

Answer 7

Weighted Arithmetic Mean

Question 8

the middle value of a given set of measurements, provided that the values or measurements are arranged in an array

Answer 8

MEDIAN

Question 9

characteristics of the median

Answer 9

1. most appropriate measure of central tendency (interval data)
2. lies between the highest and lowest measurements
3. only one value for the median in a given set of measurements.
4. not influenced by extreme values
5. It is the value where 50% or half of the distribution lies above it and 50% lies below it

Question 10

is the value which occurs most frequently in as set of measurements or values.

Answer 10

MODE

Question 11

least common among the three measures of central tendency

very useful as a measure of popularity

for ungrouped data is fairly easy to
find, the value or measurement which occurs the most number of times

Answer 11

MODE

Question 12

Unimodal

Answer 12

One mode

Question 13

Bimodal

Answer 13

two modes

Question 14

Trimodal

Answer 14

Three modes

Question 15

Multimodal

Answer 15

more than 3 values for the mode

Question 16

characteristics of the mode

Answer 16

1. most appropriate measure of central tendency (nominal scale)
2. least reliable among the three measures of central tendency
3. used when we want to find the value whish occurs most often.
4. quick approximation of the average
   node is sometimes referred to as an inspection average

Question 17

1. most appropriate measure of central tendency (interval data)
2. lies between the highest and lowest measurements
3. only one value in a given set of measurements.
4. not influenced by extreme values
5. It is the value where 50% or half of the distribution lies above it and 50% lies below it

Answer 17

MEDIAN

Question 18

1. most appropriate measure of central tendency (nominal scale)
2. least reliable among the three measures of central tendency
3. used when we want to find the value whish occurs most often.
4. quick approximation of the average node is sometimes referred to as an inspection average

Answer 18

MODE

Question 19

1. most appropriate measure of central tendency (interval or ratio)
2. lies between the largest and smallest values or measurements
3. only one value in a given set of values or measurements
4. easily influenced by extreme values

Answer 19

MEAN
