maximum
maximum m

Maximum value. The graph has a maximum point at P.

Gradient zero
Negative gradient
Positive gradient

The tangent of the curve at point P has a gradient of zero. The tangent immediately to the left of P has a positive gradient and the tangent immediately to the right of it has a negative gradient.

mean
moyenne f

Mean. The arithmetic mean of a set of numbers is the sum of all the numbers divided by their number in the set.

Often called average).

For example: The mean of 2,6,8,9,12
is:
2+6+8+9+12/5 = 37/5 = 7.4.

5

What came in the dice 6 5 4 3 2 1

Number of throws 3 3 2 4 3 5

(Total 20 throws)

And the mean of what came in the dice is:

188

20 /(1×5)+(2×3)+(3×4)+(4×2)+(5×3)+(6×3)
20 /64 = 3.2.

mean deviation
écart m moyen

Mean deviation. The mean deviation (or more precisely the mean absolute deviation from the arithmetic mean) of a list of numbers is determined as follows:

Sum of all deviations from the mean / Number of numbers in the list

For example: The mean for 7.3.10.4 is 24/4 = 6, so the deviations are 1,3,4,2. Thus, the mean deviation is equal to:

2.1/2 = 1+3+4+2 /4 = 10/4

median
médiane f

Average, median. The mean of a set of numbers is the value of the number in the middle of the set when its numbers are arranged in ascending order. Examples of this include:

The mean of the set 1,2,4,7,9 is 4.

.5 2,5,8,3,1,7,6 becomes 1,2,3,5,6,7,8 and the mean is 5.

If there is no middle number, the mean of the middle number of the set is taken instead.

For example: The mean of the set 1,5,7,8,9,10 equals

. ( 7 + 8 ) 2 = 7.1/2

The mean of the frequency distribution can be found from the cumulative frequency graph. . . cumulative frequency or the Gothic arc ogive.

member
membre m

Member. A number, letter, symbol, etc., that belongs to a set is called a member of the set. For example:

2 is a member of the set of even numbers.

And a is a member of the set of vowels.
But 4 is not a member of the set of odd numbers.

The mathematical symbols for (member of) (or belongs to) and for (not a member of) (or does not belong to) are » and »
respectively. For example:

Prime numbers ε2

Voice letters P

Alphabet letters sε

mensuration
mésure f

Measurement. Measurement of geometric quantities such as lengths, areas, and volumes.

meridian
méridien m

Circle of longitude. Meridian. A circle of longitude is a great circle drawn on the surface of the Earth that passes through the North and South Poles. For example: All lines of longitude can be referred to as circles of longitude.
