HSE104 Practice Exam

Two published articles that report on referencing error rates among exercise and sport science journals reported rates of

47% and 50% respectively

What is the value of the median for the following set of scores? (Scores: 1, 3, 5, 5, 6, 7, 13)

5

A good Discussion section includes which of the following pieces of information

A statement about the results in relation to the hypotheses; Interpretation of the findings; Summary and conclusions

An advantage of a poster presentation is that it

A sport scientist designs a study to examine the effect of a six week strength training program on maximal anaerobic running velocity (vMART) among a sample of 20 elite endurance athletes. The athletes were tested before and after the strength training program. The researcher wants to assess whether the post-program vMART scores were significantly different to those obtained pre-program. What type of statistical test would the researcher use to test for differences on the pre- and post- vMART scores?

Dependent t test

In analysis of variance, each independent variable is referred to as a ____.

Factor

The distribution for age of participants within a study are presented in the figure below. Which of the following best describes the shape (or direction of the 'hump') of the distribution?

Moderate-severe positive skew

Classifying people according to gender (male/female) would involve measurement on a(n) ____ scale of measurement.

Nominal

A researcher conducted a study to investigate attitudes of adolescents attending major sporting events towards online gambling. Her study utilised two separate methods. The first method involved a quantitative survey. Once the survey was completed she then followed this up with a number of one-on-one interviews with a subset of adolescents who completed the original survey. This research represents what type of study design?

Sequential mixed-methods design

Qualitative researchers will often sketch out a visual representation that depicts themes, sub-themes and codes by way of a

Thematic map

The term that is used to describe the quality of a qualitative study, that is how well it was conducted and analysed, is known as _________

Trustworthiness

Under what circumstances are post-hoc tests necessary?

When you reject the null hypothesis with more than 2 treatment conditions.

A correlation of -0.42 between two variables indicates

a moderate negative relationship

The numerical value for a correlation ____.

can never be greater than 1.00 and can never be less than -1.00

The purpose of a post hoc test is to ____.

determine which treatments are different

The extent to which results of a study can be generalised to the real world is referred to as

external validity

Reasoning that moves from a limited number of specific observations to general conclusions is termed ____ reasoning.

inductive

The probability of committing a Type I error ____.

is determined by the level of significance (α) that one chooses

Compared to basic research, applied research

is done in the "real world," such as the training or competition setting

in qualitative research, the process where a researcher goes back to participants to share their conclusions and see whether participants agree with these is known as

member checking

For the following set of numbers (5, 100, 104, 201,104,104, 104, 105, 212, 218, 189, 104) the value of '104' would represent which of the following?

mode

A variable that captures information about the team that a person supports (eg. in AFL - Adelaide Crows, Brisbane Lions ...) is what type of variable?

nominal

In a distribution with positive skew, scores with the highest frequencies are ____.

on the left side of the distribution

A Pearson correlation of r = -0.85 indicates that a graph of the data would show ____.

points clustered close to a line that slopes down to the right

A researcher performs a t test to determine if two groups of athletes differ on a reaction time measure. She predicts that there will be no difference between the two groups on reaction time (null hypothesis). The researcher inspects the output of the analysis and determines that the t value was - 5.31 and the associated probability was 0.02. Based on these findings, what decision should the researcher make?

reject the null hypothesis - there are group differences for reaction time

A one-way ANOVA test is used to

test whether three or more groups differ significantly

An important assumption of parametric statistical tests such as the t test and oneway ANOVA is that scores on the dependent variable have approximately equal (equivalent) variances for each of level of the independent variable or factor of interest. The results for a oneway ANOVA performed by a researcher are presented below. What interpretation should the researcher make about the variances for the independent variable/factor and whether or not there were differences among the group means?

the variances are equal and there are differences among group means

A researcher reports that there is a significant difference between two treatments at the .05 level of significance. This means that ____.

there is a 5% probability (or less) that the difference occurred simply by chance without any treatment effect

Levene's test is used to formally assess

whether group variances are homogenous

Which alpha level provides the greatest chance of committing a Type I error?

α=.10
