Scientific Process

Front 7

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.

Back 7

range

Front 8

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.

Back 8

introduction of conclusion

Front 9

A pictorial display of a set of data.

Back 9

graph

Front 10

A pictorial display of data that can be drawn when the data for both variables are continuous data.

Back 10

line graph

Front 11

A prediction of the relationship of an independent and dependent variable to be tested in an experiment.

Back 11

hypothesis

Front 12

A section of the report of an experiment that includes the data tables, graphs, and sentences that summarize any trends found in the data.

Back 12

results

Front 13

A sequence of precisely stated steps that describe how an experiment was done, including the materials and equipment used.

Back 13

procedure

Front 14

A series of equal intervals and values placed on each axis of a graph.

Back 14

scale

Front 15

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"

Back 15

title

Front 16

A test of a hypothesis. It determines if purposely changing the independent variable does indeed change the dependent variable as predicted.

Back 16

Front 17

Data that are descriptions of qualities such as shape, color, and gender.

Back 17

Hypothesis format

Front 19

Information or values determined by calculations using collected data; examples are means, medians, modes, and ranges.

Back 19

derived quantity

Front 20

The bits of information (measurements, observations, or counts) gathered in an experiment.

Back 20

Front 21

The central value in a set of data ranked from highest to lowest. Half the data are above it and half are below.

Back 21

median

Front 22

The factor or variable that may change as a result of changes purposely made in the independent variable. ( Must be measureable)

Back 22

dependent variable (responding variable)

Front 23

The general direction or pattern of the data; it is usually illustrated on a graph as a line of best fit.

Back 23

trend

Front 24

The horizontal or vertical line found at the bottom and left side of a graph

The line drawn on the left side of a graph on which the scale for the dependent variable is placed.

Back 26

vertical (Y) axis

Front 27

The most central or typical value in a set of quantitative data.

Back 27

Front 30

The part of an experiment that serves as a standard of comparison.

Back 30

Front 31

The variable that is changed on purpose by the experimenter.

Back 31

Front 32

This is the line along the bottom of a graph on which the scale for the independent variable is placed.

Back 32

horizontal (x) axis

Front 33

Those factors in an experiment that are kept the same and not allowed to change or vary.
