Statistics Vocab
This measurement is the largest data point subtracted by the smallest data point.
What is the range?
The median of the data set:
2, 3, 6, 7, 15
What is 6?
This equation is the variable "g" being subtracted by 7 to find the variable "k"
What is k = g - 7?
Or g - 7 = k
The answer to the equation 3x = 9
What is x = 3?
The answer to the equation 14 = 28m
What is m = 1/2?
This is another name for the average of a data set.
What is the mean?
The minimum of the data set:
2, 3, 6, 7, 15
What is 2?
This equation is the variable "h" being multiplied by 4 to find the variable "m"
What is m = 4h?
Or 4h = m
The answer to the equation y - 5 = 23
The answer to the equation 8c - 3c = 45
What is c = 9?
The middle value of a data set.
What is the median?
The mean of the data set:
2, 3, 6, 7, 15
What is 6.6?
This equation finds that the sum of two variables "a" and "b" is 14.
What is a + b = 14?
The answer to the equation 3x + 8 = 473
What is x = 155?
The process of getting one variable all by itself by undoing mathematical steps.
What is isolating a variable?
This data point is higher than 25% of the other data points.
What is the first quartile? (Or - what is Q1?)
The range of the data set:
2, 3, 6, 7, 15
What is 13?
This equation says that twice the variable "c" subtracted from 18 will result in half of the variable "g"
What is (1/2)g = 18 - 2c?
Or 18 - 2c = (1/2)g
The answer to the equation 48 - b = 173
What is b = -125?
The answer to the equation 1,000,000x = 72,000,000
What is x = 72?
The middle 50% of the data, found by the calculation: Q3 - Q1.
What is the Interquartile Range? (IQR)
The interquartile range of the data set:
2, 3, 5, 6, 7, 15, 15, 16, 19, 23, 72
What is 14?
(19 - 5)
Three times "v" added to eight times "x" is the same as the square of the sum of 14 and "q".
The answer to the equation 4y + 2 = 3y - 91
The answer to the equation 7f + 19 = 63 - 4f
What is f = 4?
