The atomic theory has been developed over many years due to the work of many scientists. Each time new evidence was discovered changes had to be made. Which of the following statements is true about how new evidence affects theories? A. As new evidence is found, the evidence is changed to make it better fit the existing model.

B. As new evidence is found, the theory is revised in order to make it fit the data better.

C. As new evidence is found, the theory is discarded completely and scientists start over with a completely new theory.

D. As new evidence is found a new theory is introduced that does not fit the data as well.

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
