| Intertextuality | Meaning is constantly being produced by the relationship between texts. |
| Interval level of measurement | 1. A level of measurement in which the ratios of measured values are not meaningful, which is to say that they do not correspond to similar relationships among the objects measured. The classic example of interval measurement is the measurement of temperature using Fahrenheit and Centigrade scales. If it is 80ºF in Tulsa and 40ºF in Juneau, you cannot say it is twice as hot in Tulsa. Here is one clue that this is not meaningful. Suppose we measured the temperature in Centigrade instead of Fahrenheit. The formula for converting Fahrenheit to Centigrade is C=(F-32)*5/9. So in Tulsa it is 27 C and in Juneau it is 4 C. Now it looks like Tulsa is 4 times as hot as Juneau! Yet Fahrenheit and Centigrade are perfectly equivalent and equally valid measuring scales. So you know ratios are not meaningful in interval measurement. 2. The ratios of differences (intervals) among measured values is meaningful. For example, suppose it is 70 F in L.A. and 50 F in San Francisco. The difference in temperature between Tulsa and Juneau (40 F) is twice as much as the difference in temperature between L.A. and San Francisco (20 F). This statement is still true if we measure the temperatures in Centigrade, so interval measurements preserve ratios of differences in measured values. |
| Interval measure | The level of measurement that is characterized as being mathematically isomorphic with arithmetic. All math functions for nominal and ordinal measures plus an arbitrary zero point, and equal distance between units of measurement. Statistically appropriate techniques include arithmetic mean, standard deviation, r2 Z,T,F . Examples include temperature and time measurement. |
| Interval scale | The categories are ordered and there are equal intervals between points on the scale, but the zero point on the scale is arbitrary so that a particular measure cannot be said to be 'twice as' large as another measure on the same scale (e.g. degrees Centigrade). |
| Intervening Variable | 1. An intervening or intermediary variable is one that is affected by the independent variable and in turn affects the dependent variable. 2. a third variable that is causally prior to the dependent variable, but not to the independent variable. |
| Interview | 1. A method of data collection involving an interviewer asking questions of another person (a respondent) either face-to-face or over the telephone. 2. a research method in which the researcher (interviewer) asks questions to another (respondent). Interviews are person to person and are conducted either face to face or telephone. |

Love is not just an emotion or feeling that changes when the loved one changes, but rather, it is the act of choosing to do what is in the best interest of the loved one over the long haul whether s/he deserves it or not, despite the cost to oneself and without expecting anything in return. |
