First, please see the graphic in the link. It's considered one of the best summaries of data of all time.
Why?
One the one hand, it conveys a massive amount of information about Napoleon's invasion of Russia: how his force was diminished in size, where they went, etc. Yet, on the other hand, it is easy to comprehend. Even without reading the details it's easy to understand what happened.
This is a very high standard for statistical presentation. At the same time, it's worth considering what's possible when summarising data.

Define mean absolute deviation?
The average mean absolute deviation of a data set is the average of the absolute deviations from a central point. It is a summary statistic of statistical dispersion or variability.
What is mean in data analysis?
In data analysis, the mean is a measure of central tendency that represents the average value of a dataset. It is calculated by summing all the data points and dividing by the number of points. The mean provides a useful summary of the data, but it can be affected by outliers, which may skew the results. Therefore, it's often considered alongside other measures, such as the median and mode, to gain a more comprehensive understanding of the data distribution.
What numerical summary cannot be negative?
The numerical summary that cannot be negative is the mean (average) of a dataset. While individual data points can be negative, the mean represents the central tendency of the values and is computed as the sum of all values divided by the count of those values. Additionally, measures like count, total, and standard deviation are also inherently non-negative.
Why is the mean a measure of the center of the data?
mean does not mean the center of the data

What does data consolidation mean exactly?
Data consolidation means that you take data from various different sources and in different forms and make a summary of that in the form of one entity. You are consolidating data into x.
What is a summary of a trial?
data or a paragraph about the data you have found about something
What does data analysis mean in a science fair project?
It means your summary of what u did. You'll want to have graphs, data tables, then analyze your data with calculations. Does your data support your hypothesis? That's the question you want to answer when doing your calculations.
What is the purpose of calculating the mean and the variance?
Calculating the mean helps to understand the central tendency of a data set, while calculating the variance provides information about the spread or dispersion of the data points around the mean. Together, the mean and variance provide a summary of the data distribution, enabling comparisons and making statistical inferences.
What is collect and analyze data?
collect and analize the data means to do a summary about what you learn
Define mean absolute deviation?
The average mean absolute deviation of a data set is the average of the absolute deviations from a central point. It is a summary statistic of statistical dispersion or variability.
What measure of center best represents data?
The answer depends on the type of data. The mean or median are useless if the data are qualitative (categoric): only the mode is any use. The median is better than the mean is the data are very skewed.

What is A summary that explains data?
A summary that explains data typically provides a brief overview of the key insights, trends, or patterns found within the dataset. It may include descriptive statistics, visual representations, and important findings to help readers understand the main points without having to delve into the raw data in detail.
What is the default summary function for numeric data in a PivotTable?
SUM
Which descriptive summary measures cannot be easily approximated from a box-and-whisker plot?
A box-and-whisker plot provides a visual summary of the median, quartiles, and potential outliers in a dataset, but it does not easily convey measures such as the mean or standard deviation. Additionally, it does not provide information on the distribution shape, skewness, or kurtosis, which are essential for understanding the overall distribution of the data. These summary measures require additional calculations or data representations for accurate approximation.
