Computing a s finding the number in the middle of a list of increasing numbers is the amount of change between the average (mean) and the next highest (or iowest) significant value in a sample of data. 3. The number which is the average of the highest and lowest score in a set of data is called the 4. When trying to complete a set of numerical data, use a line of to best approximate missing values.

Answers

1. Median

Hint: Median is the middle most observation of the data, determined after all items are arranged in ascending or descending order of magnitude. In other words, median is that observation above which and below which lie 50% of all the data.

2. Standard deviation

Hint: Standard deviation gives an idea of how much the observations in the data differ from the mean of the data. The variance and the standard deviation are both measures of the spread of the distribution about the mean.

3. Mid-range

Hint: Mid-range = (Highest value + Lowest value)/2

4. Regression

5. Population, sample

6. Significance, confidence

7. Datum

8. Correlation
