 The equal size values represented by the equal spaces marked along the axis of a graph, or the spaces between units of a measuring device. intervals The last section of a report of an experiment; it states the purpose, major finds, hypothesis, a comparison of the findings of this experiment with other experiments & recommendations for further study. conclusion A chart to organize and display the data collected in an experiment data table A decimal system of weights and measurements based on units such as grams,meters, and liters Metric Measurement (SI) A list of everything you need in an experiment. (Always identified on one's science board prior to explaining the procedure. (experiment) Materials A logical way to pose and answer questions or develop and solve problems in science. Scientific Process A measure of how a set of measurements or count data is spread out. It is calculated by subtracting the minimum value from the maximum value. range A paragraph at the beginning of a report of an experiment that states why the experiment was done(reason); what was expected to be learned(purpose)by doing it, and was the hypothesis proven or disproved. introduction of conclusion A pictorial display of a set of data. graph A pictorial display of data that can be drawn when the data for both variables are continuous data. line graph A prediction of the relationship of an independent and dependent variable to be tested in an experiment. hypothesis A section of the report of an experiment that includes the data tables, graphs, and sentences that summarize any trends found in the data. results A sequence of precisely stated steps that describe how an experiment was done, including the materials and equipment used. procedure A series of equal intervals and values placed on each axis of a graph. scale A statement describing an experiment or data table. These statements are often written in the form, "The Effect Of Changes in the Independent Variable on the Dependent Variable" title A test of a hypothesis. It determines if purposely changing the independent variable does indeed change the dependent variable as predicted. experiment Data that are descriptions of qualities such as shape, color, and gender. observations If ____________ (IDV)THEN ___________ ________(DV)_______________BECAUSE: Hypothesis format Information or values determined by calculations using collected data; examples are means, medians, modes, and ranges. derived quantity The bits of information (measurements, observations, or counts) gathered in an experiment. data The central value in a set of data ranked from highest to lowest. Half the data are above it and half are below. median The factor or variable that may change as a result of changes purposely made in the independent variable. ( Must be measureable) dependent variable (responding variable) The general direction or pattern of the data; it is usually illustrated on a graph as a line of best fit. trend The horizontal or vertical line found at the bottom and left side of a graph axis The line drawn on the left side of a graph on which the scale for the dependent variable is placed. vertical (Y) axis The line drawn on the left side of a graph on which the scale for the dependent variable is placed. vertical (Y) axis The most central or typical value in a set of quantitative data. average (mean) The most typical or central value of a set of qualitative data.It is the value that occurs most often in the set. mode The number of times that a level of the independent variable is tested in an experiment or the number of objects or organisms tested at each level of the independent variable. repeated trials (5) The part of an experiment that serves as a standard of comparison. control The variable that is changed on purpose by the experimenter. independent variable (manipulated variable) This is the line along the bottom of a graph on which the scale for the independent variable is placed. horizontal (x) axis Those factors in an experiment that are kept the same and not allowed to change or vary. constants a control that receives none of the independent variable, for example ( a set of plants that receives no fertilizer. no treatment control
