Team 1
The sum of the quantities divided by the number of quantities
What is Mean?
A chart that compares different categories of data using rectangular bars that represent the value of the data.
What is Bar Graph
a graph in which the values of two variables are plotted along two axes
What is scatter plot?
50th percentile of the data
What is the other name of the median?
Data type where the variables have natural, ordered categories
What is ordinal data
standard deviation divided by mean
What is Coefficient of variation
The square root of variance
What is standard deviation
It involves asking current research participants to help identify other potential subjects for a study
What is snowball sampling?
Single stage and two stage
What are the two types of cluster sampling
Where each member of the population has an equal chance of being selected
What is a simple random sampling
sampling method where researchers select members of the population at a regular interval
What is systematic sampling
This is 15 in this data:
2;5;6;9;11;17;15
What is the range of this data:
2;5;6;9;11;17;15
It is 84 for 76,85, 97, 83
What is the median for 76,85, 97, 83
It is 2 in 4, 2, 3, 4, 2, 2, 6, 7
What is the mode for 4, 2, 3, 4, 2, 2, 6, 7
It is 5 for 1,2,4,8,10
What is the mean for 1,2,4,8,10
The middle of the two sections before and after the median
What is quartile 1 and quartile 3?
a type of distribution in which most values are clustered around the left tail of the distribution while the right tail of the distribution is longer.
What is positively skewed distribution
a representation of data in the form of a map or diagram in which data values are represented as colours.
What is a heat map?
when the values of variables appear at regular frequencies and often the mean, median, and mode all occur at the same
What is a symmetrical distribution
The mean is usually greater than the median, which is always greater than the mode.
What is positively skewed data?
