Question

The measure of central tendency most affected by outlier scores is the: median. mode. Mean. none of the above. Which of the following is true about the following set of scores: 11, 18, 18, 38, 22, 14, 13, 8, 10, 6, 37: The mean, median, and mode are equal to each other. The mean is greater than the mode. The mean is greater than the median. The mode is 43. The type of graph used to show the relationship between pairs of scores is called a: stem-and-leaf plot. bar graph. frequency histogram. scatter diagram. Participants are asked to indicate their gender on a questionnaire. This an example of a(n) ___ scale. nominal ordinal interval ratio The median of the five scores 245, 274, 222, 233, and 266 is equal to: 245 222 248 52 Which of the following is an example discrete variable? number of times you visited your grandmother last month. your weight after eating a large meal. your current age. the time it takes to drive to school.

Explanation / Answer

As there are multiple questions here, I would answer the first question :

1)

The measures of Central tendency most affected by outlier scores is : Mean

Explanation :

Definitions -

1) Measures of Central tendency :

A measure that is used to describe a whole set of data by a single value i.e it represents the middle value or centre of the distribution.

There are mainly three different measures of Central Tendency :

i) Mode : A value that is repeated most number of times in a set of data is called mode.

ii) Median : A value that comes in the middle of a set of data when the set is arranged in ascending or descending order.

iii) Mean : It is the sum of all the numbers in a data set divided by total numbers of numbers in set i.e the average.

Effect of Outliers on each of the measures of tendency :

As median is the central value of a data set it is less affected by outlier scores. Morever mode is also unaffected by the outlier scores as it displays a number which is repeated the most.

But as the mean of a data set takes into consideration all the values of the set it is affected the most by outlier scores.
