In one study, half of the rats are given one food pellet each time they correctly run a maze, and the other half of the rats are
given two food pellets each time theycorrectly run a maze. The researchers record the average amount of time it takes the rats to run the maze. In this study, the number of food pellets represents the __________ variable.
independent
Researchers record the average time it takes rats to complete the maze. In this study, the number of feed pellets was independent as per Manipulation of the Independent Variable
Manipulation of the Independent Variable Again, manipulating an independent variable involves systematically altering its levels so that different groups of participants are exposed to different levels of that variable, or This means that the groups will be exposed to different levels at different times. Independent variables are variables that researchers manipulate to better understand how phenomena, structure, and behavior are related to the dependent variable and Alternative Hypothesis . Instrumental variables are the independent variables in an experiment. It's called "manipulated" because it's something you can change. That is, you can decide in advance whether to increase or decrease. Experiments should always have only one instrumental variable.
The most concerning manifestation that the nurse should be
aware of or the physician should pay attention to the physiological changes in
the neonate is its heart rate. The heart rate that are higher compared to its
normal rate should be taken action of. An example of this is when the neonate
exhibiys a heart rate of eighty eight beats per minute, if it occurs, they
should take action immediately.
