experimental group

Also found in: Dictionary, Thesaurus, Medical.

experimental group


experimental condition

the group which receives the INDEPENDENT VARIABLE in an experiment. Typically, in the EXPERIMENTAL METHOD, the EXPERIMENTAL HYPOTHESIS is tested by treating the experimental group with the independent variable to be investigated, and comparing any resultant effect (measured by the DEPENDENT VARIABLE) with any change observed in the CONTROL GROUP. If a statistically significant difference is found between the dependent measures in experimental and control groups, then the experimental hypothesis is upheld. If there is no statistically significant difference, then the NULL HYPOTHESIS is upheld.

Significant Difference between Cross-age Experimental Group and Same-age Experimental Group for Grade-III
In this study, the height of germinal epithelium in experimental group C was close to control group A with p-value of 0.214, which was statistically insignificant.
The animals of both control and experimental group A1 and B1 were sacrificed at week 5 and those in control and experimental group A2 and B2 were scarified at week 9.
Results: The mean age of the women was 30.20 +- 4.88 in the experimental group and 30.85 +- 4.47 in the control group.
The final test showed an increase in the average of 9.2 cm in favor of the experimental group, the avarage of this group being 180 [+ or -] 10.32[degrees], while the mean of the control group was 150.9 [+ or -] 11.57[degrees], the coefficient the variability being 6.48% for the experimental group and 9.59% for the control group.
In the experimental group, 25(62.5%) patients stated that they did not receive extensive information about their disease and HD, whereas this ratio was 24(60%) in the control group.
Experimental group was instructed number concepts by implementing intervention i.e., use of digital game for 30 minutes daily (five days in a week).
The objectives of the study was: (1) To assess the effectiveness of labor support measures by comparing the pain score of mothers with first stage of labor in experimental and control groups and (2) to get the verbal response of mothers in experimental group after 2 h of delivery about the effectiveness of labor support measures.
The researchers found that reduced pain, higher pressure pain thresholds at primary test site at three months, and reduced central sensitization inventory scores at six and 12 months were experienced by participants in the experimental group. These patients also experienced improved function and significant and clinically relevant reduction of disability at three, six, and 12 months.
The difference between the two groups was that the experimental group used the peer coaching-based personalized learning approach, while the control group used the expert guidance-based personalized learning approach.
Experimental group patients received hometelecare intervention for 3 months starting on the date on which patients signed the hometelecare project consent form, which was taken as the 1st day.
