Answer:
ok
Step-by-step explanation:
Answer:
With a skewed distribution and data with outliers.
Step-by-step explanation:
There are three measures of central tendency.
- Mean: It is the average value of data and affected by presence of outliers.
- Median: It is the value that divides the data into two equal parts. It is a position based measure of tendency.
- Mode: It is the most frequent observation in the data.
- For a symmetrical distribution for continuous data, the mean, median, and mode are equal.
- For such case mean is a better measure of central tendency because it includes all of the data in the calculations.
- Median is the best measure of central tendency when the data is not symmetrical because the median is position based.
- Advantage of the median:
The median is not affected by outliers and skewed data as compared to the mean.
Thus, median likely to produce a better measure of central tendency than the mean with a skewed distribution and data with outliers.
42 - 19 = 23
the difference between 42 and 19 is 23
Answer:
the range is 13
Step-by-step explanation:
Range is the largest number subtreacted from the smallest. In this case, it will be, 79-66=13
Basically if you know your addition just add the values of each coin or dollar bill. Just forget about the $ sign or cent sign when adding the values together.
FOR EXAMPLE:
$1 and $2.75
You would ignore dollar sign and add together like normal to get
3.75
But remember to add dollar sign back at the end.
If the value only have 2 values with cents it should be something like
0.54 cents BUT NO DOLLAR SIGN
Hope that helps
