Mean : Mean is the average that is within your data set, which is found by dividing up the sum of the data by the total number of data points.
It can be represented as
Example: Data set: 2, 3, 4, 4, 5, 5, 6, 6, 8, 10
2+3+4+4+5+5+6+6+8+10= 53
10 total numbers in data set
53/10
mean= 5.3
Median: The middle value in the data set.
First you must arrange the data set in least to greatest, then find the value in the middle of the set.
If there are odd amount of numbers than there is one median.
If there are an even amount of numbers there are two middle values and then you just take the average of them.
Example:
2, 3, 4, 4, 5, 5, 6, 6, 8, 10
there are an even amount of numbers so ..
5+5=10 divide by 2. = 5
median= 5
Mode:
The most common value in the data set
4, 5, 6 are the most common values in the data set because they all appear twice.

your examples were really clear and easy to understand!
ReplyDeletethis helps me understand the mean, median, mode a lot better!
ReplyDeletesam,
ReplyDeletegood lesson and nice job of explaining mean, median, and mode. an addition to make the lesson connect to real life would be to add a real world example to these numbers, but otherwise, good job.
