(11, 8) 4. Treated the same as the experimental group except for the factor that is being investigated. This allows comparison. (7, 5) 5. Measurements will have very little spread about the mean value. Smallest scale on a measuring device. (9) 6. Measurements that fall outside of the expected measured values. Large number of readings allow anonymous data to be identified. (9, 4) 7. A change in one variable is caused by a change in another variable. (6, 4) 10. Repeat experiments increase reliability of the mean. If other scientists get the same results, then the results of the initial investigation will be more reliable. (11) Down 2. A variable that may affect the outcome of the investigation. Must be kept constant throughout the investigation or the effects of the independent variable will not be shown. (7, 8) 3. This is the likelihood of an even occurring, and can be expressed mathematically. (11) 6. Free from errors and close to the true value (8) 9. A relationship between two variables, however it may not be a casual one. (11)
