Mean-average found by
adding numbers in a list &
dividing by amount of
numbers. (i.e. 4,1,3,2,10
4+1+3+2+10=20÷5=4
The Mean is 4
Range- difference between
highest & lowest number.
(i.e. 3,4,5,6,7,8
8-3=5)
Mode-number that occurs
most often (i.e.9,2,5,6,9,2,
Mode is 2 and 9)
Average-Mean or Mode of
data.
“Inverse” – means opposite.
Eg the inverse of addition is
subtraction.
“Recurring” – means
repeating. A recurring
decimal can never be worked
out exactly and has
repeating pattern of
numbers (i.e. 1/3 is 0.3333)
“Inverse” – means opposite.
Eg the inverse of addition is
subtraction.
“Intersecting” – means lines
that cross each other
“Congruent” – means exactly
same shape and size as one
other.
“Vertex” – means corner or
tip. Plural is vertices.
“Translation” – in maths
means moving a shape in a
certain way. Eg Up/Down
Left/Right but shape must
be congruent (same).
“Approximately” – means not
an exact answer.
“Radius” – distance from
centre of circle to edge.
“Circumference” – distance
all the way around circle.
“Perimeter” – distance all
the way round the edge of a
shape.
“Numerator” – top number
of a fraction telling us how
many parts out of the total.
(i.e. ⅞ the 7 is the
numerator)
“Denominator” – bottom
number of a fraction tells us
the number of equal parts
something has been divided
into. (i.e.⅛ the 8 is the
denominator)
“Improper fraction” – a top
heavy fraction where the
numerator is larger than the
denominator. (i.e. 8/7)
“Equivalent” – same as.
“Percentage” – out of 100
(%)
“Quotient” – number of
times one number can be
divided into another.
Eg. 10÷5=2 so the quotient
is 2.
