What is the meaning of a manipulated variable?
== == A 'manipulated' variable can be what is called an independent variable in a research setting. Say that I want to know what medications will be most effective in helping people suffering from infection-related stomach ulcers. I have several volunteers who will be in the study, divided into equal groups. I could do any of the following: study one single med and vary the doses across groups with one control group receiving a placebo; I could study several different meds, and perhaps even have various dose-groups for each of them as well if I have enough groups of appropriate size, or I could compare naturopathic or dietetic treatments with meds. In all of these cases the variations in treatment protocols represent the manipulated variable. The dependent variable, the treatment outcomes, are how the volunteers do in the various groups. Statistical analysis will help determine how significantly (if at all) the groups differ from one another, and this will help determine relative effectiveness of the treatments.
What is the constant variable in investigation of fungi growth mold?
The constant variable in investigating fungi growth mold could be the temperature, humidity level, or type of substrate being used for growth. This variable remains unchanged throughout the experiment to ensure that any observed differences in growth can be attributed to the independent variable being tested.
What do control groups and experimental groups have in common?
Yes in a way, and no in a way. In a blind study, the control group will be the group that is administered the placebo, the sugar pill, while the experimental group will be treated with the actual medication (if this is a study on how a medication affects something). That way, the researchers can see what side effects are real or not (obviously people on the sugar pill will not be experiencing nausea as a cause of the pill but rather because their mind thinks they are).
How does maldistribution occur?
Mal-distribution can occur due to various factors such as unequal access to resources, inadequate infrastructure, limited awareness about available opportunities, or political and economic disparities. These factors contribute to the unequal distribution of resources, wealth, and opportunities among different regions or groups within a population, leading to mal-distribution.
What is one of the values of a variable which divides the distribution of the variable into four groups having equal frequencies?
quartile
One of the values of a variable which divides the distribution of the variable into four groups having equal frequencies?
Quartile
What a quartile?
quartile- one of the values of a variable that divides the distribution of the variable into four groups having equal frequencies.
What is one of the values of a variable which divides the distribution of the variables into four groups having equal frequencies?
quartile
What is one of the values of a variable which divides the distribution of the variables into three groups having equal frequencies?
A tertile or tercile.
What goes on the X-axis of a frequency polygon?
The X-axis of a frequency polygon typically represents the variable being measured or categorized, such as age groups or test scores. It is a horizontal axis that shows the range of values for the variable. Each interval or category is usually evenly spaced along the X-axis to show the distribution of data points.
Who divides a group of data into two groups?
Jack divides his groups into two.
What is a frequency table?
A frequency table is a way of tabulating data, where the independent variable (that is, what you are measuring, such as height or length) is listed in the left hand column. The frequency, which is the number of times the independent variable occurs, goes on the right hand column. Sometimes, we represent the frequency by means of tally marks. A grouped frequency table groups the independent variable into "classes": e.g. 0 - 5, 6 - 10, 11 - 15...
What are quartiles?
In statistics, a quartile is each of four equal groups into which a population can be divided according to the distribution of values of a particular variable.
What is decile?
Decile means one of the ten groups containing an equal number of the items that make up a frequency distribution.
What variable is the factor that the experimenter deliberately changes across these groups?
The variable that the experimenter deliberately changes across groups is the independent variable. This variable is manipulated to observe the effect it has on another variable, known as the dependent variable.
What groups are non security-related groups created for the distribution of information to one or more persons?
Distribution
