Question

Write the definition for each terms at length.

 

1. The Distribution of a Variable

2. Frequency Tables

3. Differences Between Groups or Conditions

4. Correlations Between Quantitative Variables

5. Scatterplots

Answer 1

1. The Distribution of a Variable:-if you perform a number of trials then the Distribution of a Variable is defined as the description of relative numbers of time each possible outcome will occur in the number of trials.

2.Frequency Table:-a frequency table is a table that lists items and uses tally marks to record an show the number of times they occur.

In other words, in statistics there is a chance for a particular value to be repeated in a set of data.the number of times the particular value is repeated is called frequency.the table based on data values with their corresponding frequency is called frequency table.

3. Differences Between Groups or Conditions:-differences between groups show how two or more groups are different from each other.

4.Correlations Between Quantitative Variables:-variables that can be measured on a numeric scale are termed as quantitative data.Correlations Between Quantitative Variables is defines as the relationship between the variables.we can measure the extent to which they are related by correlation coefficient.

5. Scatterplots:the simplest mode of diagrammatic representation of bivariate data is the use of scatter plot or scatter diagram.taking two perpendicular axes of coordinates one for x and other for y,each pair of values are plotted as a point on the graph.the whole set of points taken together constitutes a scatterplot.
