1. POSITIVE CORRELATION
} A
positive correlation is a relationship between 2 variables where if one
variable increase, the other one also increase. A positive correlation also
exists if one decrease, the other also decrease.
EXAMPLE:
} The
more time you spend running on a treadmill, the more calories you will burn.
} The
taller people have large shoe sizes & shorter people have smaller show
sizes.
} The
longer your hair grows, the more shampoo you need.
2. NEGATIVE CORRELATION
} A
negative correlation means that there is an inverse relationship between the
two variables- when one variable decrease the other increase. The vice versa is
a negative correlation too, in which one variable increase and the other
decrease.
EXAMPLES:
} A
student who has many absence has a less in grade.
} If
a train high speed the length of time to get to the final point short.
3.
ZERO CORRELATION
} No
correlation occurs when there is no linear dependency between the variables. A
correlation is a score which shows that there is no relationship/ link between
two things.
EXAMPLES:
} The
more weight I gain the smarter I will be (intelligence is not effected by
weight)
} Cookie
sales and temperature (Cookies are an all your treat so they do not go up or
down depending on the temperature)
