 * Team 2's Response to Standard Deviation Exercise**

 Standard Deviation is a measure of variability that helps to understand that an average mean is not always the best measurement of differences between two variables; to describe how far the data are spread around a mean; the mean cannot fully describe a set of data. Standard Deviation uses the square of the distance to the mean and provides a more reliable way to interpret the differences between two variables than just adding all the points from the mean together.

A large standard deviation indicates that the data points are far from the mean and a small standard deviation indicates that they are clustered closely around the mean. It may indicate the precision of measurements if the mean of the measurements is too far away from the prediction (with the distance measured in standard deviations). If this occurs, the theory being tested probably needs to be revised.

Our team will use standard deviation with our data analysis. From reviewing the raw data, it appears that the respondents answered questions relating to the barriers of purchasing green cleaning products as we predicted.
