Final answer:
To fill in missing numbers on a decimal grid, identify the numerical patterns and apply them to find the missing values. For statistical tables, use operations and statistical concepts to calculate relative frequencies, probabilities, and percentiles.
Step-by-step explanation:
When filling in the missing numbers on a decimal grid pattern, you should mainly rely on b) looking for patterns and relationships between numbers. This involves recognizing how the numbers are changing across rows and columns—whether they are increasing, decreasing, consistent, or following a mathematical operation such as addition, subtraction, multiplication, or division. Once a pattern is identified, you can apply that pattern to calculate missing values.
For example, if you notice that each number in a row is increasing by 0.5, you would add 0.5 to the last known number to fill in the next missing number. If you are given a table with values that represent a statistical distribution and asked to calculate the relative frequency and cumulative relative frequency, or if you need to find probabilities and percentiles, basic operations and knowledge of statistical concepts such as mean, median, quartiles, and standard deviation will be essential to solving the problem correctly.
