A researcher collected data from a sample of 20 participants in a pilot study on the relationship between locus of control and self-esteem. Scores on the locus of control scale range between 0 and 25; a higher locus of control score indicates a more external locus of control. Scores on the self-esteem inventory range from 0 to 40; a higher self- esteem score indicates a higher level of self-esteem. The raw data are shown below. For this set of data: 1. Identify the predictor and criterion variables. 2. Determine the mean and standard deviation of the predictor and criterion variables. 3. Draw a scatterplot of the data.

Concept explainers

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Question

Please answer all the parts. please include all the steps.

A researcher collected data from a sample of 20 participants in a pilot study on the
relationship between locus of control and self-esteem. Scores on the locus of control
scale range between 0 and 25; a higher locus of control score indicates a more external
locus of control. Scores on the self-esteem inventory range from 0 to 40; a higher self-
esteem score indicates a higher level of self-esteem. The raw data are shown below. For
this set of data:
1. Identify the predictor and criterion variables.
2. Determine the mean and standard deviation of the predictor and criterion variables.
3. Draw a scatterplot of the data.
4. Calculate the Pearson r for this data set.
5. Write a short summary interpreting your descriptive and correlational results in
both technical language and plain English.
