Question

1. a survey group conducted a study to determine if there is an association between the age of a person and the average number of emojis used per text. the survey results are below. age and emojis used per text

age	15	28	36	10	62	47	23	14	16	20	40	33	50	42	30	12	30	68	70	54
average number of emojis used per text	10	8	5	9	1	1	7	9	8	6	3	4	2	2	6	10	3	6	0	1

a) create a scatter plot using the data in the table.
b) what type of association do the two variables seem to have? no association positive linear association negative linear association non - linear association
c) does there appear to be an outlier? yes no if yes, where? yes
d) based on the data, what can you say about age and the number of emojis used per text?

Explanation:

Step1: Create scatter - plot

Plot age values on the x - axis and average number of emojis used per text on the y - axis for each pair of data points from the table.

Step2: Determine association type

As age increases, the average number of emojis used per text generally decreases. So, it is a negative linear association.

Step3: Check for outliers

Visually inspect the scatter - plot. There may be points that are far from the general pattern of the other points. For example, some points may deviate significantly from the general downward - sloping trend.

Step4: Analyze relationship

The data suggests that younger people tend to use more emojis per text, while older people tend to use fewer emojis per text.

Answer:

a) (Scatter - plot should be created manually on graph paper or using graphing software with age on x - axis and emojis on y - axis for each data pair)
b) NEGATIVE LINEAR ASSOCIATION
c) (Answer may vary depending on visual inspection. If there are points far from the general trend, list the corresponding age and emoji - count values. For example, if a point with age 10 and 10 emojis is far from others, note it. But generally, visually assess and state the coordinates if any.)
d) Younger people tend to use more emojis per text, and older people tend to use fewer emojis per text.
