(2.3)(-0.5)
SHOW YOUR WORK and if you do i'll give you brainiest :)

-1.15

Step-by-step explanation:

(2.3)(-0.5), parenthasese mean multiply and the other parenthases are just there cuz itz negative. if its wrong lemme know and ill redo and chat the answer im just a little rusty at this

The answer is option E "mean, median, standard deviation, and IQR"

Step-by-step explanation:

Step 1: An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean.

Step 2: The most common measure of variation, or spread, is the standard deviation. The standard deviation is a number that measures how far data values are from their mean.

Step 3: The standard deviation provides a numerical measure of the overall amount of variation in a data set, and can be used to determine whether a particular data value is close to or far from the mean

Step 4: Given the change in the values of all the data set, it implies that each of the values of mean, median, standard deviation and IQR is going to change.
