Error intervals are crucial in understanding the limits of accuracy when dealing with rounded or truncated numbers. This concept is essential in GCSE maths and beyond, helping students grasp the range of possible values a number could have had before rounding or truncation. Understanding error intervals in math involves identifying the smallest and largest numbers that would round or be truncated to a given value for a specific degree of accuracy.
• Error intervals provide a range of possible values for rounded or truncated numbers.
• They are expressed as inequalities, showing the minimum and maximum possible values.
• The concept is important in various mathematical and practical applications.
• Calculating error intervals requires understanding place value and rounding rules.
• Error intervals help in assessing the precision of measurements and calculations.
