BIO2110L Quiz Cumulative Review

In Inferential Statistics we use__________________________________________.

• sample means to predict community guidelines.

• sample error to predict future parameters.

• sample selection to predict natural selection.

• sample statistics to estimate population parameters.

How can variables be classified? What are the 2 types of variables used in statistics?

• -Categorical: Nominal & Ordinal

  -Numerical: Discrete & Continuous

• Quantitative and differential statisitcs, uses one variable continuously.

• Providing a thorough qualitiatve description, disregarding percent error.

• Modifying the order through statistical means.

In the context of a study/experiment variables can also be classified as...

• Continuous and discrete

• Numerical and discrete

• Explanatory and response

• Ordinal and numerical

True or false: Explanatory variable is the variable being affected, whereas the response is the variable causing an effect.

• TRUE

• FALSE

There are many ways to plot data points in statistics, how do we select a graph to use to plot data?

• Data means and statistics

• Number of variables and Data types

• Data values and regression lines

• Linear correlations and regression lines

True or False:

Frequency is a variable that can be commonly represented on the y-axis.

• TRUE

• FALSE

This plotted data set represents what type of data table?

• Histogram

• Contingency Table

• Grouped Bar Plot

• Bar Plot

What type of data table is used to display this data set?

• Histogram

• Contingency Table

• Bar Plot

• Grouped Bar Plot

What type of graph is used to display this data set?

• Contingency Table

• Grouped Bar Plot

• Histogram

• Mosaic Box Plot

When creating a scatterplot to go alone with a simple linear regression analysis

• Def not this one

• predictor variable = Y axis, response variable = X axis

• predictor variable = X axis, response variable = Y axis

• Trick question, only one variable is used
