coefficient of determination
Unemployment rate measures the percentage of the labor force that is currently unemployed and actively seeking employment. It is an important economic indicator that provides insight into the health of the job market and overall economy.
One quarter (25%) of us will have a collision this year. Defensive driving skills give us the opportunity to reduce our chances of being one of those 25%. In reality, this means that an average driver will have one collision every four years. A defensive driver greatly reduces that probability.
According to the World Health Organization, pedestrians account for about 23% of all traffic fatalities worldwide. This highlights the importance of pedestrian safety measures to reduce the risk of accidents involving pedestrians on the road.
The literacy rate measures the percentage of people in a population who are able to read and write at a specified age or stage of schooling. It is often used as an indicator of a country's educational development and overall level of human capital.

It measures associations between variables.
measures of variation
line that measures the slope between dependent and independent variables
In regression analysis, the t-value is a statistic that measures the size of the difference relative to the variation in your sample data. It is calculated by dividing the estimated coefficient of a predictor variable by its standard error. A higher absolute t-value indicates that the predictor is more significantly different from zero, suggesting a stronger relationship between the predictor and the response variable. This value is used to assess the statistical significance of the predictor in the regression model.
by how can you find measures of variation?
how the annual percentage rate measures the true cost of a loan
Inter-quartile range, other percentile ranges, mean absolute variation, variance, standard error, standard deviation are all possible measures.
There are a number of appropriate displays to show the measures of variation for a data set. Different graphs can be used for this purpose which may include histograms, stemplots, dotplots and boxplots among others.
Compensating variation and equivalent variation curves show the relationship between changes in income and the associated changes in consumer surplus. Compensating variation measures the amount of income needed to keep a consumer at the same utility level after a price change, while equivalent variation measures the amount of income needed to achieve the same utility level as before the price change. These curves help analyze the welfare impact of price or income changes on consumers.

standard deviation only measures the average deviation of the given variable from the mean whereas the coefficient of variation is = sd\mean Written as "cv" If cv>1 More variation If cv<1 and closer to 0 Less variation
