All of these depend on the person who is making the observation someone else might make these measurements differently. Other information which may go in the title, if available, includes: the date, place and name of experimenter or collector of the data. The standard deviation is small when the data are all concentrated close to the mean, exhibiting little variation or spread. A: The independent variable is the cause or variable that is changed while the dependent variable is, A: Hi, Thanks For Your Question. The ability to make inferences and predictions based on data is a critical skill students need to develop. 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). Hows an analyst to choose?

Most graphs have 5 major parts: Title Independent Variable (X-axis) Dependent Variable (Y-axis) Box plots show distribution based on a statistical summary, while column histograms are great for finding the frequency of an occurrence.

That is, just presenting a series of data as randomnumbers that bear little apparent relationship to one another is often difficult to interpret. Charts and graphs allow a person to visualize data and find patterns and trends in the data. People who specifically study the growth patterns and socioeconomic characteristics of human populations are called ___. D. Place the dependent variable on the Y-axis. Students Join your classmates! Graphs are easy to construct, easy to read, and do not presuppose a level of significance necessary to evaluate the significance of the study. Many graphs are used to concisely and clearly summarize data; the best type of graph to use depends on the type of data being conveyed (such as nominal, scale-discrete, scale-continuous and ordinal). b) Is the vaccine protective against dying composed with the place to (control)? answer choices The dependent variable is not labeled correctly There is too much data on this graph and it should easier to read. The variance may be calculated by using a table. Changes inseveral different samples can be shown on the same graph by using linesthat differ in color, symbol, etc.
