Seven lists that follow a data unit
Under Start from a list, Center and Spread has Quartile, Variance and Percentile beside the three averages. Surveys and Samples has Population, Bias, Stratified and Convenience. Statistical Graphs names the pictures, from Dot plot and Box plot to Scatter plot, and Parts of a Graph has Axis, Interval and Bin.
Kinds of data, shapes and trends
Kinds of Data sets Categorical beside Numerical and Discrete beside Continuous. Shapes of Data has Skewed, Bimodal and Bell curve. Trends and Conclusions has Correlation, Residual and Causation for a scatter plot lesson.
Box plot, Scatter plot, Bell curve and Frequency table hide closed up: BOXPLOT.
Easy Statistics has 42 words of three to five letters, such as Mean, Mode, Data, Poll and Bias.
Tick Show clues, not words and Median prints as "The middle value once the data are put in order."
Questions and answers
What is an outlier in statistics?
A value that lies far away from the rest of the data. One very large or very small value pulls the mean toward it, while the median is not skewed by a few extreme values.
What is the difference between a bar graph and a histogram?
A bar graph shows categorical data, with one bar for each category. A histogram shows number data: the range of values is divided into intervals, called bins, and each bar counts the values that fall in one interval.
What is the difference between a population and a sample?
A population is the whole set a question is about. A sample is a part of it, chosen to stand for the whole. A number that describes a population is a parameter; one worked out from a sample is a statistic.
