in an experiment, the condition that is tested because it affects the outcome of the experiment
the outcome factor; the variable that may change in response to manipulations of the independent variable
Statement of Problem
the first step in the scientific method and should provide clearly a basis an rationale for conducting research
Possible explanation for a set of observations or possible answer to a scientific question
identical to the control group, except one factor which is compared to the control group
observations that deal with descriptions that cannot be expressed in numbers
a branch of applied mathematics concerned with the collection and interpretation of quantitative data
Statement of Problem
Cannot be a yes or no question, the independent and dependent variable have to be included, the problem has to clearly be able to be tested, and the response is written clearly, and specifically
Has to predict a trend, has to take a stand to one side of prediction, has to include both the independent and dependent variable, has to have a rationale
All materials used are listed,no more no less, the materials are separate from the procedure
Is logically sequenced, well organized, enough information for the experiment to be repeated, diagram should be included, the trials should be stated
Observations about results and the procedure are given, have to be from throughout the experiment,cannot relate directly to the dependent variable
Quantitative Data (Data Table)
All the raw data given, all data has units, most important information is included, the table is labled correctly, example calculations are given
The type of graph is good for the experiment, the graph is titled, the graph is labeled correctly(axes/series), units are included, the correct scale is used
The average, median, mode, range, and line of best fit are included, measure of central tendency, measure of variation, regression analysis, etc.
Analysis and Interpretation of Data
All data is discussed about and interpreted, any unusual points are discussed, trends are explained, and enough details given to understand data
Possible Experimental Errors
The possible reasons for errors are given, valid information about how the data was taken is included, the effect that the errors had on the data is discussed
Hypothesis is evaluated based on the data, the hypothesis is re-stated, the reason to why the hypothesis is rejected or accepted is included, all statements are supported by the data
Applications and Reccomendations for Further Use
Suggestions for that specific experiment, for other ways to look at the hypothesis, for future experiments are given; practical apllications of the experiment are also given
The number that, in a set of data, is either very high or very low and is no where close to the other numbers/points in the data
The vector direction that tells how much displacement there is in a certain amount of time( velocity=displacement/change in time)
A measured distance or dimension(merriam--webster) or how long something is from end to end(chalk.richmond.edu)
