Investigating skills

Question 1

Independent/ input variable:

Answer 1

variable that you change

Question 2

dependent/ outcome variable:

Answer 2

changes as a result of independent

Question 3

controlled variable:

Answer 3

variable you keep constant

Question 4

hypothesis

Answer 4

a prediction to the outcome of your experiment based on logic and research.
statement
specific
variables involved- cause and effect
testable generalization

Question 5

table

Answer 5

heading- includes variables
independent variable comes first
units at top table no units in table.
arrange data in descending order of independent variable

Question 6

graphs

Answer 6

heading- variables
dependent variable- y axis+ units
independent variable- x axis+ units

Question 7

Linear relationships

Answer 7

line graphs go up straight line

positive linear relationship, as one variable increase so does the other

Question 8

negative linear relationship

Answer 8

graph line decreases,

as one variable decrease, so does the other decrease.

Question 9

direct proportional graph

Answer 9

graph straight line increasing starting at zero

means one variable is zero so is the other, the variable increase in equal increments.
