Type of study
The entire group of individuals or instances about whom we hope to learn, whole group.
What is Population? ( This is not a type of study )
The sample group is chosen from the population who are readily available or 'convenient'.
what is Convenience Sample?
the arithmetic average of a distribution, obtained by adding the scores and then dividing by the number of scores
What is Mean?
a graphical representation showing the five-number summary of data
What is Box Plot (Box and Whisker Plot)?
a graphical device that summarizes data by the number of dots above each data value on the horizontal axis
Whta is Dot plot?
A study that uses counts or measures of the entire population.
What is Census?
Each member of the population has an equal probability of being selected as part of the sample group.
What is Simple Random Sample?
the middle score in a distribution; half the scores are above it and half are below it
What is Median?
A value that "lies outside" (is 1.5 times smaller or larger than) most of the other values in a set of data.
What is Outlier?
An analytical technique that accounts for the number of acceptable errors in an experiment.
What is Margin of Error?
A study that selects a subset of the population to estimate the characteristics of the whole population.
What is Sampling
A population is divided into groups, then ALL members of one or more (NOT ALL) of the groups are selected as part of the sample group.
What is Cluster Sample?
the most frequently occurring score(s) in a distribution
What is Mode?
the difference between the first and third quartiles
What is Interquartile Range (IQR)?
An average of the particular items or individuals included in a particular study. Abbreviated with a lowercase x with a horizontal line over top (called 'x-bar')
what is Sample mean?
A study based on data in which no manipulation of factors has been employed.
what is Observational Study?
The population is ordered in some way and even nth member is chosen for the sample group.
what is Systematic Sample?
the difference between the highest and lowest scores in a distribution
What is range?
consists of the minimum and maximum, the quartiles Q1 and Q3, and the median
What is a 5 number summary
A hypothesis which predicts no difference between the results from the different conditions of an experiment.
*EXPECTED RESULTS
What is Null Hypothesis?
A study based on data that manipulates factor levels to create treatments, randomly assigns subjects to these treatments
what is Experimental Study?
The sample group is chosen from the population who are readily available or 'convenient'.
What is Convenience Sample?
An experimental study that is done in such a way that both the primary researcher and the subjects (patients) do not know which subjects are receiving he placebo or the actual treatment. This is done to ensure the results are not affected by a placebo effect and also helps ensure that the researcher doesn't have bias.
what is double blind?
A hypothesis which predicts difference between the results from the different conditions of an experiment. This can mean something is different, incorrect, or has changed. ( unexpected result )
what is Alternative hypothesis?
A hypothesis which predicts difference between the results from the different conditions of an experiment.
This can mean something is different, incorrect, or has changed.
*UNEXPECTED RESULT.
what is Alternative hypothesis?
