How do you find the range when your median is 20?

There is no direct relationship between the range and the median. So knowing that your median is 20 does not automatically give you the range. The median is just the middle value. That does not tell you what the first and last values are, which is what you need to know to find the range. The median of 19, 20 and 21 is 20, and the range is 2. The median of 4, 20 and 79 is also 20, but the range is 75. The median of 8, 16, 17, 23, 50 and 320 is also 20, but the range is 312. So, as you can see, the Median in no way can tell you what the range will be. You need to know what all of the numbers are, or at least the lowest and highest to know the range.

What is trend and correlation?

A trend refers to the general direction in which something is developing or changing over time, often observed in data or market behavior. Correlation, on the other hand, measures the strength and direction of the relationship between two variables, indicating how one may change in relation to the other. While a trend can show an overall pattern, correlation quantifies the degree of association, which can be positive, negative, or nonexistent. Understanding both concepts is crucial in data analysis and forecasting.

What factors to consider when investigating a variance?

When investigating a variance, consider the magnitude and direction of the variance to understand its significance. Analyze underlying data for accuracy and potential errors, and assess any changes in processes or external factors that may have influenced the results. Additionally, evaluate historical trends and performance benchmarks to contextualize the variance within a broader framework. Lastly, ensure that stakeholder input is gathered to provide insights and perspectives on the observed discrepancies.

How many 9 digit numbers which are divisible by 4 can be formed by using the digits 1 to 5 if repetition of digits is allowed?

Reqd no. is 9 -digits.. available digits are 1 2 3 4 5.. Numbers which are divisible by 4 can be determined by the last two digits.. from the given combinations,, the numbers div by 4 are 12, 24, 32, 44, 52

so.. the number's last two digits can be any of the above 5.

Hence, we have to calculate the combinations for the first 7 digits..

Ans: (5C1)^7 * 5
