Across
- 2. involves analyzing two separate variables and is used to determine whether or not two variables are related.
- 5. a change over time
- 6. line of best fit/ a straight line that describes how a response variable y changes as an explanatory variable x changes
- 8. a measure of how dispersed the data is in relation to the mean
- 11. uses dots to represent values for two different numeric variables
- 12. The difference between the lowest and highest values
- 15. A histogram is a graphical representation of a grouped frequency distribution with continuous classes.
- 16. the measure of the steepness and the direction of the line
- 19. the average distance between each data point and the mean
- 20. The first quartile (Q1, or the lowest quartile) is the 25th percentile, meaning that 25% of the data falls below the first quartile.
- 21. a measure of the asymmetry of a distribution.
- 22. In statistics and mathematics, the deviation is a measure that is used to find the difference between the observed value and the expected value of a variable
- 23. In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.
- 24. In mathematics, a univariate object is an expression, equation, function or polynomial involving only one variable
- 25. The 5 numbers in the five-number summary are lower extreme (minimum), the lower quartile (Q1), the median(Q2), the upper quartile (Q3), and the upper extreme (maximum).
- 26. A box and whisker plot or diagram (otherwise known as a boxplot), is a graph summarising a set of data
Down
- 1. A data distribution is a graphical representation of data that was collected from a sample or population
- 3. an extreme value in a data set that is either much larger or much smaller than all the other values.
- 4. a statistical measure of the strength of a linear relationship between two variables
- 7. a relationship between two events where one event is affected by the other.
- 9. A special point that usually has some symmetric placement with respect to points on a curve or in a solid.
- 10. a measure of statistical dispersion, which is the spread of the data
- 13. A dot plot is a graphical display of data that emphasizes the overall shape of quantitative data.
- 14. how spread scores are in a distribution out
- 16. the form of an object or its outline, outer boundary or outer surface
- 17. Second Quartile/ middle
- 18. describes the relationship between variables
