Question

Cali has gathered extensive data regarding the stress levels workers with green cards in five U.S. cities. She arranges the data from low to medium to high and notes how many workers with green cards are in each category using a bar chart. This is called a ____.

Answer 1

Answer:

b. frequency distribution

True. By definition a frequency distribution is "representation that shows the number of observations within a given interval" usually with the intervals ordered from the lowest values to the highest values.

So on this case this is the representation for the procedure described.

Step-by-step explanation:

Assuming the following options:

a. standard deviation

False, the standard deviation is a measure of dispersion from a dataset and is given by this formula:

$s= \sqrt{\frac{\sum_{i=1}^n (x_i-\bar x)^2}{n-1}}$

b. frequency distribution

True. By definition a frequency distribution is "representation that shows the number of observations within a given interval" usually with the intervals ordered from the lowest values to the highest values.

So on this case this is the representation for the procedure described.

c. normal distribution

False

The Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

And for this case is not related with the procedure described

d. median

False. the median is a value from a distribution who represent the 50 percentile or a value that accumulates 50% of the data below.

And for this case we can't associate the median with the procedure described.
