Part B: CREATING A NEW DATA FILE AND EXAMINING RELATIONSHIPS.

The following data represent the results of descriptive research on the ability to solve mazes in preschool children. The researchers tested 60 children with the same maze, and recorded the number of errors each child made while solving it. Each child's age and gender were also recorded.

4-year-old girls: 12, 9, 13, 7, 10, 8, 11, 9, 10, 124-year-old boys: 9, 13, 14, 11, 9, 9, 10, 8, 7, 10

5-year-old girls: 9, 7, 8, 11, 6, 7, 9, 7, 5, 85-year-old boys: 10, 6, 7, 8, 9, 8, 11, 5, 8, 7

6-year-old girls: 3, 2, 5, 3, 4, 3, 6, 1, 3, 46-year-old boys: 1, 5, 4, 2, 2, 4, 3, 2, 3, 3

Input these data into an Excel spread sheet and bring into JASP as a CSV file.

1. Which format should used to input the data -column or row format? _column_____

Think about IVs and DVs and create proper variables for each aspect of the given data.

Obtain the mean, median, mode, skewness using the descriptives function

2. Who has the highest average number of errors scores when splitting on sex? Girls

Make a distribution plot of this data and show the density curve.

3. Which sex has a more normal curve?

3a. What function/value did you use to answer this question?

Split the data on age.

4. On descriptive statistics which group has the highest amount of errors?

5. Is each group normally distributed?
