TeacherVisionis part of the Sandbox Learning family of educational and reference sites for parents, teachers and students. The standard deviation can be used to determine whether a data value is close to or far from the mean. The independent variable is type of treatment and the dependent variable is plant growth (in cm). Scatter plots are best for showing distribution in large data sets. Remember that standard deviation describes numerically the expected deviation a data value has from the mean. He, as do many of his science colleagues, states that the scientific method has four steps: 1) observation and description of a phenomenon or group of phenomena; 2) formulation of a hypothesis to explain the phenomena (in physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation); 3). The measurement is determined by the object that is being measured. Line graphs are the best type of graph to use when you are displaying a change in something over a continuous range.
