What does it mean to say that data has a strong negative correlation?
ra1l [238]

indica que as duas variáveis movem-se em direções opostas, e que a relação também fica mais forte quanto mais próxima de menos 1 a correlção ficar. Duas variáveis que estão perfeitamente correlacionadas positivamente (r=1) movem-se essencialmente em perfeita proporção na mesma direção, enquanto dois conjuntos que estão perfeitamente correlacionados negativamente movem-se em perfeita proporção em direções opostas.

HELPPP ASAPPPPP!!!!!! PLEASE :(
goldfiish [28.3K]

Step-by-step explanation:

A bar graph serves to visibly represent the frequency of a series of events.

To create a bar graph you can draw on the horizontal axis, each one of the events, and on the axis to verticate the frequency of occurrence.

For this case the possible events are the values from 1 to 5 of the numbered sequence

1 2 3 4 5

The frequency for each number is

4 6 2 6 2.

With these values, a bar graph was made in excel, which is shown in the attached image.

There it is observed that the events with greater frequency are the 4 and the 2.
