Question 131327
Determine the mean, median, mode, and midrange of the set of data. Round your answer to the nearest tenth.
============================== 
a) 7,5,8,8,8,10,12 
The mean represents the average or the sum of the data divided by the number of pieces of data : mean = 58/7 = 8.2857
--------
The median is the value in the middle of a set of ranked data 
median = 8
-------------------
The mode is the piece of date that occurs most frequently
mode = 8
----------------- 
The midrange is the value half way between the lowest and highest
values in a set of data. It is found by adding the loweast and highest values and dividing the sum by 2.
midrange = (5+12)/2 = 8.5
====================================
================================== 
b) 1,1,1,1,4,4,4,4,6,8,10,12,15,21 
The mean represents the average or the sum of the data divided by the number of pieces of data
mean = 92/14 = 6.57...
----------- 
The median is the value in the middle of a set of ranked data 
median = 4
-------------
The mode is the piece of date that occurs most frequently 
You have two modes: 1 and 4 ; the data is said to be bimodal
-----------------
The midrange is the value half way between the lowest and highest
values in a set of data. It is found by adding the loweast and highest values and dividing the sum by 2.
midrante = (1+21)/2 = 11
