IGCSE Grade 6 Maths Finding the range
|
To find the maximum and minimum values, we can arrange the numbers in ascending order:
123,234 234,445 304,564 333,098 556,345 789,567 889,567
The minimum value in the set is 123,234, and the maximum value is 889,567.
Now, we can calculate the range by subtracting the minimum value from the maximum value:
Range = Maximum value - Minimum value = 889,567 - 123,234 = 766,333
Therefore, the range of the given set of numbers is 766,333.
To find the range of a dataset, we need to calculate the difference between the maximum and minimum values in the dataset.
Since each measurement is a randomly generated integer between 1 and 1000, the maximum possible value is 1000 and the minimum possible value is 1.
The range of the dataset will be the difference between the maximum and minimum values:
Range = Maximum value - Minimum value = 1000 - 1 = 999
Therefore, the range of the dataset is 999.
Difference of largest and smallest number
To find the range of a dataset, we need to calculate the difference between the maximum and minimum values in the dataset.
In this case, we have 100 measurements, out of which 5 are incorrect and have been replaced with the value 10. Therefore, we need to consider the possibility that the maximum or minimum values could be the incorrect value of 10.
The possible scenarios for the maximum and minimum values are:
The maximum value is less than 10 if the incorrect measurements are not among the largest values.
The minimum value is greater than 10 if the incorrect measurements are not among the smallest values.
The maximum value is 10 if one or more of the incorrect measurements are among the largest values.
The minimum value is 0 if one or more of the incorrect measurements are among the smallest values.
Considering these possibilities, we calculate the range in each case:
If the maximum value is less than 10 and the minimum value is greater than 10: Range = Maximum value - Minimum value < 10 - 10 = 0.
If the maximum value is 10 and the minimum value is 0: Range = Maximum value -
Minimum value = 10 - 0 = 10.
To find the range of a dataset, we need to calculate the difference between the maximum and minimum values in the dataset.
Since each measurement is a randomly generated integer between -500 and 500, the maximum possible value is 500 and the minimum possible value is -500.
The range of the dataset will be the difference between the maximum and minimum values:
Range = Maximum value - Minimum value = 500 - (-500) = 1000
Therefore, the range of the dataset is 1000.
In this case, we again need to determine the difference between the largest and smallest values in the data set. The smallest value is -2.3, and the largest value is 2.6. So, the calculation is as follows:
Range = Largest value - Smallest value Range = 2.6 - (-2.3) Range = 2.6 + 2.3 Range = 4.9
Thus, the range of the given data set is 4.9.
number lie between the highest and lowest marks
difference of smallest and largest number
greatest number = 200 smallest number = 50
To find the range of a dataset, we need to calculate the difference between the maximum and minimum values in the dataset.
Since each measurement is a randomly generated decimal number between 0 and 1, the maximum possible value is 1 and the minimum possible value is 0.
The range of the dataset will be the difference between the maximum and minimum values:
Range = Maximum value - Minimum value = 1 - 0 = 1
Therefore, the range of the dataset is 1.
