The answers are given below:-
- If the data is symmetrical, then the mean is the best measure of central tendency to use, and the standard deviation is the best spread to use.
- If the data is unsymmetrical, the median is the best measure of central tendency to use, and the inter-quarterly range is the best spread to use.
<h3>What are symmetrical and asymmetrical data?</h3>
A histogram for symmetrical data will give a symmetrical shape, and the mean, median and mode will all be the same value. Therefore, the best measure of the central tendency to use is the mean. The standard deviation shows how far away the values in a given data set are from the mean, and since the mean is used as the measure of central tendency in this case, the standard deviation should be used as the spread.
A histogram for a an asymmetric data set will give an asymmetric shape, and the mean is not always equal to the median. Therefore, the best measure of central tendency to use is the median. The inter-quarterly range shows the range of the middle 50% of a certain data, which is considered from the median value. Since the median is used as the measure of central tendency in this case, it is wise to use the inter-quarterly range as the measure of spread.

The delivery fee is 25 dollars and each shirt is 10 dollars
That’s not math that’s a bunch of bull shi!t
To write the rule or equation of the linear function we need to find the slope of the function first. Using any two points we can find the slope.
Using the first two points (-3, -1) and (0, 2).
Slope (m) of the function would be:
Using slope and the point (0,2) we can write the equation of the line as:
y - 2 = 1(x-0)
y = x + 2
Thus, the correct rule for the given linear function is x+2
